Background: Changbin was much like the other kids growing up in the East. He had parents, of course, but then, suddenly, he didn't. The most that he remembers from the start of it all is fire, and a lot of it. He doesn't know it but a fire was set to the house to burn the dead bodies of his parents who had crossed the wrong person. Feeling sorry for the kid, the arsonist got him out of the house and to safety. He cried a lot and clutched his teddy to his chest. Most people, namely people from the West, don't believe there are emergency services in the East. There are. They just aren't as responsive. Changbin was taken to a police station after some volunteer firefighters put out the fire, although not before the fire spread to the houses on both sides. Changbin wasn't the loudest of kids and all he really knew how to do was to ask for something to eat, something to drink and a blanket. He ended up making something of a home of one of the jail cells in the small police office, which lasted the kid a few years before the police station was shut down thanks to some higher ups in the East had considered the precinct to be a waste of money. He was out on his own in the streets, 5-years old, with no relatives to care for him.

Changbin wandered around, stealing food and just trying to survive. It was pretty easy for him to get food and temporary shelter since most people felt sorry for the young kid, even more so since he didn't seem to know many words. He kept his teddy bear with him the entire time, refusing to let it out of his sight and hold since it had become something that kept him calm; It earned him all of his bear-related nicknames. Even by the time he was 12, he was still only asking for food, drinks and blankets, only introducing himself as Binnie as it was easiest for him to remember and repeat, although he never forgot his actual name. How he survived, or even why, didn't make sense to him or anyone else. Changbin couldn't read or write and he had no one to take care of him, hiding out in empty buildings to sleep when he could. That was until he found a home that he thought was empty, only to meet Hyunjin. It started with Hyunjin just giving him a blanket and a meal but that was enough to cause Changbin to keep coming around since he felt comfortable and safe with the other. Meeting Hyunjin changed Changbin's life around and, for the better. He's unaware that he turned Hyunjin's life around for the better as well. Their repeated meetings, which were really just Changbin asking for some food and a place to sleep, grew into Hyunjin taking time to teach Changbin to read and write; the younger began looking out for him as well. Changbin became more expressive the more he learned and understood, though yelling as though he's still a child has stuck with him. When he gets too emotional, he can't think straight and he's not the best at forming sentences to convey his thoughts and emotions, which is why he tends to be more physical in such instances.

Thanks to Hyunjin, Changbin has gotten to try a lot of things he never thought he could do. That includes things small things like trying new foods and actually reading books on his own to learning ways to channel his emotions although he still has trouble sometimes getting them out calmly with his words. It's one reason why both he and Hyunjin have so many tattoos. Changbin was also adamant about giving more and more to Hyunjin because he realized that Hyunjin wouldn't scratch at the tattoos, meaning his best friend wouldn't hurt himself. Music became another one of the easiest ways for him to express himself. It was even easier with Hyunjin supporting him and financing things for him along the way. Changbin was always excited to get out and show his music and learn from others. Thanks to Hyunjin's grandfather, Changbin was able to go to music shows in the West and meet with and learn from various artists. Being from the East made it a bit difficult to keep in touch with all of them but, thankfully, there were also some from the East. One of his most notable connections, a guy named Christopher, earned him a spot in the band, Diamonds in Moonlight.

Being a member of the band was where he learned more about producing and playing and maintaining instruments. He and Christopher got very close, very quickly, but things weren't at their high forever. As things seemed to grow tainted in their paradise, Changbin grew closer to Jungkook and they eventually left the band together. They've been together ever since. They couldn't leave music altogether though so they eventually worked on starting a new one together. Thus was Crown for the Preachers born. Although Changbin considers the band, Hyunjin and Hyunjin's grandfather as family, they are also like two different worlds for him. He takes on much more of a father role when he's with the band, wanting to protect all of his kids, while he's more in baby mode with Hyunjin.

Other relationships with other characters:
Christopher/Chan: They became best friends easily and they both thought that would never end, especially with all the work they did together in music. After Jonghyun's passing, their paths just seemed to start to split and it ended up with Changbin being stabbed when he tried to talk the other through it. Changbin kind of regrets giving up so easily on being there for him but it was clear that Chan had made up his mind and chose his addictions over him. He hasn't spoken to him since that day.
Jungkook: Changbin treats him like a baby and Jungkook soaks it up even though they're much older now. They met in DiM and haven't split from each other's sides since then. They started their current band together and plan to stay together for as long as they can.
Hun: Members of DiM together before the big split. He thought highly of Hun for sticking through things and watching over the group. He knows that Hun had something to do with Chan going to rehab. Although he keeps in touch with Hun, he doesn't ever talk about DiM with him or Chan.
CyA: They didn't really get the chance to know each other, even more so with how young CyA was when they met and the fact that Changbin was leaving the group around the time of the younger joining. He doesn't talk to him much only because they don't know each other all that well but he's made it clear on more than one occasion that CyA's welcome to talk to him if he ever wants to.
Taemin: Baby number two for Changbin. Taemin gets as much babying as Jungkook does even though Taemin is the same age as Changbin. They're much closer than people think and, when they all crash together somewhere for a night, such as to be closer to a venue for a show, Taemin is one of two that are usually found curled up with or near Changbin. The other would be Jungkook.
Hongjoong: He isn't Changbin's kid but feels a lot like his other half on most days. It's like they're the parents of their band, with Hongjoong feeling like Changbin's parental figure when Hyunjin isn't around. Changbin is very glad the group found him and feels like he was the missing piece. He tells Hongjoong often that he's thankful for the other being there for all of them all the time. He doesn't know the entirety of Hongjoong's story but knows he's been through a lot and is just thankful that he keeps a level head for the rest of them.
Yeonjun: Kid number three. Yeonjun is the kid that, if they all were an actual family, people would expect him to grow up like Changbin. They're very playful with one another and go back and forth with friendly bickering from time to time, though it's always in good fun. They both can be quite aggressive and have a tendency to wrestle one another on any given occasion. Changbin thinks highly of him just like he does his other's members. He feels like he'll never be able to forgive himself for Yeonjun getting hurt by Wooyoung, wishing he'd gotten them separated somehow sooner when he could see the telltale signs of Wooyoung's addiction problem.
Wooyoung: Changbin wouldn't necessarily say he hates Wooyoung but it's pretty darn close. He used to love and adore him like he was another one of his kids but, when Wooyoung ignored his warning and chose addiction over their band family, he already began to cut ties and suggested that Wooyoung be removed from the group to work on himself. In the midst of it all, Wooyoung ended up somewhat reenacting his scene with Chan and it both scared and broke him, even more so since it felt like he was reliving his situation with Chan all over again.
