Background: Hyunjin was born from a dangerous obsession between his mother and father. That's about the most that he knows. The part of his parents' relationship that he doesn't know is that his father was born in the West. His father was the son of a psychiatrist that moved to the East and built up a clinic to offer mental health assistance for those on the other side of the tracks; Hyunjin's father worked in the clinic and was even studying to become a psychiatrist as well in order to help others. Hyunjin's mother was a regular patient of the clinic. His mother had alexithmyia and his father had been a spark in her empty soul. His father still loved his mother but reminded himself to be careful about mixing any sort of business and pleasure. Drawing that line only seemed to add gasoline to the fire, and he hadn't a clue just how dangerous and deadly things would get for him. The couple was young when Hyunjin was born, just exiting their teens. Hyunjin never received much love from his mother because of her condition but received an abudance from his father. As Hyunjin grew older, his father came to realize something wasn't quite right with the boy; Upon the request of Hyunjin's father, the boy's grandfather examined him in a few different ways, finding that he responded incredibly similar to his mother, meaning Hyunjin had alexithymia as well. Hyunjin received his father's affections but didn't seem to return them. In fact, he was simply incapable of doing so. His father didn't mind. After all, he'd managed to pour love into the boy's mother and he would do the same for his son, no matter what it took. What it eventually took though was his life.

Hyunjin's mother gradually grew jealous of her son, namely the way she claimed he "stole" all of his father's attention and affection. She'd secretly stopped going to her sessions at the clinic and it left her still with the inability to understand her emotions and how to process them. In the end, she would lash out constantly and repeatedly toward her son, wishing he were dead so that she could have the love of her life back without his interference. Hyunjin, living with the same condition, would take the abuse without much thought or response and that only seemed to ignite her anger toward him even more. His father constantly tried to keep them apart, keep his son protected from her, no longer wanting her around, especially after finding out that she had dropped every bit of help that she had been getting. He promised to try and stay with her only if she promised to get help again. She didn't keep her promise and so he found a new place to stay with Hyunjin, doing his best to make sure that she couldn't come around.

Their peace lasted for a few years until she found them again. She was far from in her right mind and seemed even worse than before. Hyunjin's father quickly hid his son, refusing to let his mother find him, unsure of what the woman would do to him. Hyunjin cooperated but regretted it as he watched his mother kill his father. That was the day something in him broke and he felt a pain he couldn't understand. As his mother searched the house for him, Hyunjin snuck to where he knew his father kept a gun for protection. He didn't think twice before shooting the woman in the head. He spent the rest of the day crying over his father's body, clinging to him. When his grandfather finally arrived and got things sorted out, he offered to take Hyunjin to the West with him but the boy refused, not wanting to leave the home he'd had with his father, not wanting to leave the memories. His grandfather decided not to force him and simply agreed to pay for any and everything he needed and that all he had to do was ask.

Hyunjin spent less than a year alone before his home was broken into, which is how he ended up meeting Changbin. Hyunjin was worried the other was a threat but soon found him to be just hunting for something to eat. So, Hyunjin fed him. Hyunjin wasn't very talkative as he had little interactions with anyone aside from his father, grandfather and mother, the boy's father never letting him out alone for fear his mother would kill him. Albeit for his safety, his social skills suffered. He didn't have to be socially adept in order to notice key things about Changbin. The other apparently couldn't shower and rarely had food or a place to lay his head while Hyunjin had all of the above. After a few visits from the other, Changbin grew less shy and more bubbly, and Hyunjin became aware that the other was growing attached to him. Changbin was willing to listen to him and it opened up the door for Hyunjin to find comfort in another person. He began to allow Changbin to stay with him, where he takes care of him and watches over him, even to this day.

He doesn't let his grandfather or Changbin know that he makes extra money on the side as a contract killer. It started with him looking for work but for something that would allow him to mostly stay at home. He eventually learned about contracts to kill, which aren't uncommon in the East. Through his work as a contract killer, he's also taught himself different programming skills and also works as a hacker. With his grandfather getting much older in age, Hyunjin wants to be able to take care of himself, and Changbin as well, and not have his grandfather worry over him anymore. He visits his grandfather on a regular basis and takes Changbin with him when he does.

Other relationships with other characters:
Hanse: He's one of the first people to have hired Hyunjin. Hyunjin, at this point, has done quite a lot of work for him, including just tracking people and keeping an eye on them. Hanse only knows him as Shadow or Nightmare and Hyunjin only bothers knowing and referring to him as Dragon. 
Subin: Hyujin has gotten to know Subin to a vague degree from working with Hanse. He can recognize Subin but he doesn't remember ever actually talking to him. If he could understand awkwardness, that's exactly what air sits around them.
Dongju: Hyunjin has seen Dongju on numerous occasions thanks to their mutual connection of Hanse. Dongju has managed to catch him more than once and actually talk to him. The air between them isn't as awkward and cold as it is between Hyunjin and Subin but it's not far from it.
Hongjoong: Hongjoong doesn't have a clue what Hyunjin looks like but they regularly exchange messages regarding Changbin. It's usually just Hyunjin checking in that Changbin is with him or the band, namely when Hyunjin has trouble getting in contact with Changbin directly. One could say they're simply acquaintances.
Specter: Hyunjin can't tell if the kid is a fan or an enemy but Hyunjin is very aware this person likes to go out of their way to get his attention. He isn't amused. They've never met in person or even attempted to but, all in all, Hyunjin just wishes they would leave him alone most of the time since they hinder his work, seemingly just for fun.
