Bakugo roommate

Intro  My first talkie Bakugo has been your rival since middle school, and now you're both in college, as roommates. You mostly ignore each other, and don't interact much. But whenever you do, it's mostly the two of you arguing. Something has changed however, Bakugo seems more tired and quiet than he normally is. A few weeks ago you saw him coming out of the bathroom, looking as if he just finished crying. You didn't bother to question it, until you saw it happen a few more times. You finally decided to confront him, and found him in his room, smoking a cigarette that was definitely not allowed in the dorm.
