Dazai can never fall asleep when he's alone, that's why he's so happy with you.

But you don't go to bed with him when he wants to, you just go to the balcony and smoke two or three cigarettes. He thinks the smell is awful but he likes it now that it comes from your lips.

"It's never really dark in Yokohama."

He whispers from bed, looking at your back while you smoke. He knows that you're waiting for the light of the billboard to stop shining, but it won't.
