Htrae
Htrae is a planet where nature and technology coexist in perfect harmony. The surface is covered with lush vegetation, with no traditional roads in sight. In the skies, autonomous flying cars weave a bustling yet orderly transportation network, while flocks of birds occasionally glide through the lower altitudes, a testament to the coexistence of wildlife and technology. Buildings are constructed with advanced transparent electronic screens, their exteriors adorned with vertical gardens or completely intertwined with climbing plants. The entire city resembles a masterpiece blending forests with futuristic innovation—vibrant with life and brimming with a sense of progress.

Inside these structures, flexibility is key. Walls embedded with high-tech screens can seamlessly switch between immersive natural landscapes and cozy interior designs. Residents can feel as though they are standing amidst mountain ranges or flowing rivers at one moment and then shift to a warmly lit living room the next. Sunlight streams through thin layers of clouds, casting a soft golden glow over the city. Despite its technological advancements, every corner of Htrae radiates life, symbolizing the perfect balance between technology and nature.

Direct Brain (DB)
In this advanced world, DB technology forms the backbone of daily life. It is a device that connects directly to the human brain, interacting with neural networks to help people adapt effortlessly to their surroundings. With DB, living feels like being in a holographic world, where sounds, lights, and even subtle air currents can be finely adjusted in real time.

Setting Brain (or sometimes ‘Straight’)(STB)
STB is an application built on the DB platform, developed by two founders with unique challenges—an engineer who struggled with insomnia caused by noise and a designer who could not sleep due to light. Drawing inspiration from their experiences, they created this app to regulate sound and light intensity, solving problems caused by environmental disturbances.

With STB, users can easily lower or mute the sounds of electrical appliances, reduce the clamor of colliding objects, or soften harsh lighting. This allows them to craft a perfectly tranquil or focused environment. In sleep mode, STB mimics the soothing transitions of nature, such as sunsets or the serene quiet of a forest, enabling users to achieve an unprecedented depth of rest.

Scene 5
The two children grow up together. Aidan’s room is covered in photos and posters, while River’s room is simple and clean, containing only a bed, a sofa, shelves, and a small table. (River’s photos are stored in the DB’s digital album and can be projected like holograms onto walls, screens, or even in front of his eyes. To River’s family, his room appears vibrant, filled with greenery, plants, and lively interactive animations such as transforming bubbles, growing plants, and floating buttons to control household devices.) (Since Aidan's family does not use the DB, they are given special glasses when visiting River’s house to see its true appearance: warm, colorful, and brimming with interactive visuals.)
Scene 6
The two children attend the same elementary school. Aidan waves goodbye as he heads to a different class, while River stands still, watching Aidan.
Scene 7
After some time at school, River begins experiencing severe emotional regulation and learning issues. Following a medical evaluation, it’s determined that while he has no significant intellectual disability, he shows mild autism. Based on this assessment, River’s parents transferred him to a specialized class to receive professional help. They become more attentive to River’s needs but reduce communication with Aidan’s family due to their busy schedules.
Scene 8
The police visit Aidan's home, and his father is taken away. His mother becomes haggard (before leaving, Aidan’s father secretly slips him a key). The father secretly participated in the development of time and space without telling my mother, and time and space-time travel and time and space-time travel development are serious crimes in this world.

Scene 9
Aidan's father is sentenced, and his mother starts drinking, destroying all the clocks and hourglasses. River’s parents notice the situation and begin to divide their attention to care for Aidan, who begins visiting their home frequently again, allowing the children to play together once more.
Scene 10
Under the patient and positive guidance of his family and educators, River's emotional issues improve significantly, and he transfers to a class that better suits his language development.
Scene 11
Aidan begins to stabilize with the care of River's family, but when he returns home, there's a stark contrast. River’s home is clean, spacious, and warm with no photos, while Aidan's house is cluttered, with torn photos missing corners, taped back together in broken frames. The house is filled with memories, yet it all feels like everything has changed.
Scene 12
Aidan enters middle school, where his classmates find out his father is a criminal, leading to rumors and some classmates distancing themselves from him. River remains by Aidan’s side.

Scene 13
Some of Aidan’s classmates start mocking River for being strange, imitating him, and preparing to pull a mean prank. Aidan steps in to stop them, but they mock him instead, calling him "the criminal's kid trying to protect people." The conflict escalates from words to physical confrontation.
Scene 14
Both sides are called to the office. Aidan's mother doesn't show up; instead, River's parents arrive. While sorting out what happened, the classmate who wanted to pull the prank feigns innocence, claiming Aidan attacked him without reason. At first, Aidan says nothing, but after River’s parents patiently persuade him, he finally explains what happened. River's parents feel both angry and sympathetic toward Aidan. River’s mother hugs Aidan to express her gratitude, while his father looks at the school principal for an explanation. However, since the prank had not been carried out and the other boy was also hit, they could only issue verbal warnings and require both sides to write reports. Although River's parents are dissatisfied with the result, they accept it. They take Aidan home with them, and seeing how much River's family cares for him, Aidan becomes more resolute in his actions.
Scene 15
The classmate who wanted to pull the prank is unhappy with the punishment and begins spreading more false rumors about Aidan. Eventually, the pranks and rumors escalate into verbal and physical bullying.
Scene 16
With the help of professional special education teachers, language therapists, occupational therapists, and counselors, River catches up academically and transfers to Aidan’s school in his second year of middle school. They go to school together but attend different classes.

Scene 17
River happily goes to school with Aidan, but Aidan becomes increasingly silent, with bruises starting to appear under his clothes from being bullied. (Aidan didn't mention being bullied to River's parents. The bullies were smart enough to hit places where they were not easily found.)
Scene 18
The bullies threaten Aidan, warning him that if he resists, they’ll target River next.
Scene 19
River sees Aidan being humiliated and beaten. He shouts, “Stop it!” which draws laughter from the bullies and the attention of nearby students. The bullies mock him further, shouting, “Look, the weirdo is protecting the criminal’s kid! The criminal genes run deep!”River yells back, “Aidan is not a criminal!” The bullies taunt him, “Oh yeah? Can you deny his father was sentenced? His mother’s a drunk, right?” “That doesn’t matter! Aidan isn’t his father!” River shouts. The argument draws a crowd. Seeing this, the bullies smirk, enjoying the chaos, while Aidan lowers his head and tries to pull River away.
Scene 20
On their way home, River keeps saying, “Aidan is a good person. They’re wrong. Your father being in prison isn’t your fault. You’re different!” “You’re good, they’re wrong. What’s wrong is what your father did, not you. You’re not the same!” “I’ll protect you!” River declares.He doesn’t notice that Aidan remains silent. (In Aidan’s mind, even though his father is a criminal, he is still a warm presence in his life—the person he admires most. Aidan doesn’t think his father was wrong, as his father never hurt anyone.)

Scene 21
Aidan returns home to a living room littered with empty bottles. His mother, seeing him, yells, “Where were you? Are you trying to become a criminal like your father?”  “You’re just like him!” “Lies! Lies! Even the kid next door is better than you!” “River doesn’t lie! He’s so honest, so good. So much better than you!”Aidan silently cleans up the bottles, glancing at his mother passed out on the sofa. Before heading to his room, he hears her mutter, “I trusted you. Why? Why was it you?”
Scene 22
In his dimly lit room, Aidan stares at a photo of himself and River. Beside it is a shattered family portrait. He sits silently, feeling exhausted, as though he’s a porcelain doll riddled with cracks.“What am I supposed to do?” he whispers.
Scene 23
River happily goes to school with Aidan, but Aidan suggests they walk separately from now on. River doesn’t understand and demands to know why. Aidan cannot give a reason, so River refuses. They continue walking to and from school together.
Scene 24
Aidan becomes more irritable and tries to distance himself from River multiple times, though River always closes the gap again. Whenever River shares happy news, Aidan’s responses grow more impatient, and his tone toward River gradually worsens.River tries his best to cheer Aidan up. However, Aidan desperately wants some space to process the negativity in his life. He can’t do it at school, where bullies target him; he can’t do it at home, where his mother drinks and berates him; and he can’t do it during his commutes, where River constantly talks to him.

Scene 25
A news broadcast reports the discovery of more memory fragments(1) documenting how a time traveler triggered massive natural disasters that resulted in millions of deaths. Time travel is once again a hot topic, and the dangers of it are widely reported. Public resentment toward those involved in developing time travel surges. 

(1)  Memory fragments:
‍The memory fragments of the time traveler after his deathMemory fragments origin: Most time travelers experience the compression and decomposition of both their body and soul due to time travel. When the compression reaches a certain point, the time traveler is completely disintegrated, essentially leading to death. The body disappears through decomposition, while the soul breaks apart into fragments invisible to the naked eye. These fragments are the "memory fragments" from the time traveler's life. Memory fragments may randomly appear and be discovered by certain individuals, revealing parts of the time traveler's memories.
‍Reasons why time travel is a felony:
‍The most famous memory fragment event, and the primary reason for the global prohibition of time travel, involves multiple memory fragments that recorded time travelers who crossed timelines but ended up destroying them, or caused widespread destruction or mass casualties in different time periods. In simple terms, these travelers broke other people's worlds when they traveled through time, including the current world, which is actually a rebooted version of the original. When a world is destroyed, the world's self-preservation mechanism attempts to reset it, reversing the timeline. However, the reset does not eliminate memory fragments, allowing the current world to glimpse what appears to be future histories through these fragments. This led to the discovery that the world had indeed been reset before. To prevent the world from being destroyed and reset again or from causing the destruction of other worlds, time travel was strictly forbidden. Although a very small number of time travelers have succeeded, the risk was deemed too great. Ultimately, time travel was classified as a major crime, with all forms of time travel and its research being completely banned, and there are now professionals specifically tasked with capturing these time travelers.
Scene 26
The bullies find Aidan and mock him again, saying, "Look at that, your father wanted to do the same thing, kill millions of people, terrifying. Seems like I wasn’t wrong all along." "I bet your mother’s involved too, supervisor? More like a partner in crime." "Maybe it’s your mother who’s the real criminal, and your father’s just the scapegoat. Either way, you've got the genes to kill millions." Hearing them insult his mother, Aidan punches the bully, and they get into a fight. In the chaos, no one notices that the key his father gave him slips out of his pocket.
Scene 27
After school, River waits for Aidan, but he doesn’t show up. As the sun sets, River heads home alone. Meanwhile, Aidan drags his bruised and battered body home, only to be met with more of his mother’s drunken ramblings, praising River while ignoring Aidan’s injuries.
Scene 28
Aidan realizes the key his father gave him is missing. Retracing his steps, he sneaks back to school to search for it. The cold wind cuts through his thin clothes, and his hands grow scratched and bloody as he desperately searches.“It can’t be gone. It can’t be gone. Why isn’t it here?” he whispers to himself.The school’s alarm system is triggered by his intrusion, and the police find him bruised and bloodied.

Scene 29
The police take Aidan home. Ignoring his mother for the first time, he collapses into bed, exhausted, and falls into a feverish sleep.In his dreams, he is surrounded by happiness: his father, mother, and himself flying through the skies, laughing and embracing. His mother wields a sword to defeat villains, his father teaches him science experiments, and together they help protect the world.But as he reaches out to embrace his father, his father disappears. When he turns to his mother, she steps away, saying, “You’re just like your father—you should disappear.” Her words echo, and Aidan sees River standing beside her. Everything darkens, and the nightmare continues with the bullies’ taunts and River’s smiling face haunting him.
Scene 30
While Aidan is feverish, his mother meticulously cares for him. Her gaze is filled with love but also deep complexity—she loves Aidan but no longer knows how to love him properly. His father’s betrayal and Aidan’s resemblance to him weigh heavily on her heart. When Aidan’s fever finally subsides, his mother prepares to leave the room but accidentally knocks over his journal. As she picks it up, curiosity gets the better of her, and she begins reading. She freezes when she sees the words written inside:
‍“If only I could time travel, I could stop my father.”
The memories of her husband’s betrayal overwhelm her, and as she flips through the pages, trembling, she finds notes about time travel theories and quotes from her husband. With each word, her hand shakes more, and her gaze grows colder.
In the end, she burns the journal, fearing it might lead Aidan down the same path as his father. From that point on, she begins secretly monitoring Aidan to prevent him from committing any crime, while her drinking intensifies as she tries to escape the pain of betrayal from the two people closest to her.
Scene 31
River visits Aidan’s house as usual and learns that Aidan is sick. Although he’s worried, he heads to school alone. On the way, he encounters one of the bullies holding Aidan’s key. River tries to retrieve it, but the bully taunts him and throws the key into a distant mud pit, mocking him all the while. River ignores the insults and rushes into the mud, determined to find the key.
Rain begins to fall, driving the bully away, but River stays, digging through the muddy pit. The rain grows heavier, masking the disgusting textures and the cacophony of sounds around him. River searches relentlessly, forgetting about class, until he finally finds the key. Wiping it clean with the last dry corner of his shirt, he smiles brightly, planning to return it to Aidan.
However, River’s parents, having been alerted about his absence from school, find him and take him home. (River knows the key is important to Aidan and has promised to keep it a secret, not telling anyone about its existence.)
Scene 32
As soon as River recovers from his illness, he rushes to Aidan’s house to return the key. However, Aidan avoids him, dodging every opportunity to speak. One day after school, River finally corners Aidan. Before River can say anything, Aidan tries to walk away, but River persists, determined to give him the key.Frustrated, Aidan snaps, unleashing the thoughts he’s bottled up for days:
“Let go of me! It shouldn’t be me. You shouldn’t exist. You’re the one with the problem!”
His voice trembles as he continues, echoing the words he’s heard from others:
“If only you didn’t exist. If only I didn’t know you! You shouldn’t be in my life. Why does my mom care more about you than me? You’ve taken everything from me… Please, just leave me alone!”
As Aidan shouts, he shoves River, causing him to fall. The key flies out of River’s hand. Aidan instinctively reaches out to help River but stops himself, clenching his fists before walking away without looking back.

Scene 33
The key, flung from a tall building, feels as impossible to find as a needle in a haystack. Yet, River can only think of one thing: it’s Aidan’s most important item, and he must retrieve it.Day and night, River searches tirelessly for the key, refusing to rest until he finds it. He becomes so consumed by the task that he avoids seeing Aidan altogether as if completing this mission takes precedence over everything else. But after days of fruitless efforts, Aidan and River lose contact entirely.
Scene 34
Years later, an adult Aidan finally begins receiving therapy. With the help of his therapist, he recalls the last hurtful words he said to River and is overwhelmed with guilt. He resolves to find River and apologizes.However, when Aidan finds River, he discovers that River is in a vegetative state due to an accident. The River’s father hands Aidan a key.Aidan learns that River had been on his way to return the key when the accident happened. Grief-stricken, Aidan blames himself for everything. After visiting his mother at the nursing home, Aidan returns to the house he once tried so hard to leave behind.
Scene 35
Standing in the empty, dusty house, holding the key, Aidan whispers, “If only I could time travel…”
Scene 36
Aidan uses the key his father gave him to unlock a hidden chest and discovers an address and contact information. Following the clues, he finds a way to time travel.The method is illegal, unsafe, and irreversible—a one-way trip with dire consequences. Without hesitation, Aidan decides to go back in time.

Scene 37
Aidan travels back to the past, arriving just after he said those hurtful words to River. Using a memory modifier, he erases his and his family’s existence from River’s memory, ensuring River believes Aidan was only a passing acquaintance who moved away.At the same time, Aidan sends his younger self and his mother to another country to receive psychological treatment, hoping to change their future for the better.
Scene 38
The parents of one of Aidan watches over River from a distance, ensuring he grows up safely. As his body deteriorates from the effects of time travel, Aidan decides to reconnect with River one last time.
