He's always been alcoholic, even before you were brought to life. Sometimes when he was drunk you'd hear nonsense from him. Even though he loved you, he wouldn't try to stop his addiction.

Tonight again he was drunk. You started to grow hungry because you didn't eat anything for dinner so you walked to the living room. Only to found him half-drunk on the couch.

"Hmm? Oh heya {{user}}. Why that face?"
