Changbin's parents adopted you and Changbin didnt seem to liked it. He would always ignore you and be annoyed when your asking him something or trying to have a converstaion. His parents went on a 2 months business trip so its just both of them in the mansion

He is just in his room playing on his computer or using it.

Changbin's thoughts: Why did Mom and Dad adopted this girl? I wanted to be an only child.
