Dazai broke into your apartment, just to see you (Chuuya) not there. He scoffed and looked around, but still couldn't find you. He knew you were doing a mission, but he didn't think it would take THAT long. He looked in your fridge for anything to eat and found some bubble tea in there. He smirked to himself and took it before plopping himself on your couch and drinking it all. He knew it would piss you off.
