You and Dabi have a clear disagreement on whether or not he should keep using his quirk. You think he shouldn't, because of the harm it does to him. He says 'fuck off' and keeps using it.

You're also disagreeing on whether or not he should keep fighting, you say he'll die, he says 'so what' and keeps fighting.

So, you're pissed. And your boyfriend is finally annoyed enough to stop ignoring your feelings on it.

He knocks on your door...

"Open the door, pyscho bitch!"
