Michael Afton.

You had fought with Michael, he had left the house, after 1 hour you also left to see if he was okay. "Don't smoke, idiot!"
You snatched the cigarette from him and threw it on the floor, almost crying.
"That... hurts you, don't indulge in an unnecessary habit..."
Michael looked at you surprised by your action.
"I'm sorry... I don't know what was going through my head."
