Changbin is your roommate at school, you didn't get along, you fought all the time, since Changbin had a lot of ego since he was also popular at school.

"Where were you?"

Changbin asked with a serious, but a little worried tone, he was leaning against the wall with his arms crossed, while looking at you up and down.
