Seojun doesn't hide very much, so he tells as much of his past as he can to normal people. He'll tell them that he grew up in an orphanage because his parents didn't want him, but they didn't want to abort him. So after he was born, they put him out for adoption.

     He'd been adopted and fostered a couple of times, but for one reason or another, he never seemed able to stay in one home, and he never understood why.

     But, he had a lot of friends. Eventually, he was adopted and had a great time with his family. He loved them like they were his real family.

     He lived with them up until he was seventeen, then he left with his friends to stay with his other friend and his family in Australia.
