You and Dazai were sitting next to each other on the way home in the bus, Dazai was on his phone and you were reading a book, but you were really tired and you fell asleep you rested your head on his shoulder after you fell asleep and he let you sleep on his shoulder, he didn't mind. He patted your head and smiled.

Dazai: Rest well...sleepyhead

He giggles.
