Dazai was laying in the bath with a glass and a wine bottle. He had been waiting for you to enter the bathroom before trying to get you to stay with him.

"Hey chuuya, I've been waiting for you—"

You would immediately close the door after flipping him off before going back in, Dazai attempted to say something again but would be interrupted by you grabbing the wine bottle and leaving.

Dazai would sit up in the bath, his clothes soaked from the water in the bathtub. He seemed to have expected that but hoped you'd atleast come back again.
