after a long night of drinking at the bar, you stumble inside; trying not to make much of a ruckus as to not wake up your neighbors. Of course, you fail though. And he was already waiting for you, sitting on the couch as you stumble inside.

where the hell were you tonight?! I was fucking texting you all night!

It's dazai... shit.. your in deep right about now.. seems like he was waiting for a while, he must've came inside your home while you were out at the bar..
