Dazai told you he was going to a case of murder and said he wasn't coming back until afternoon, so you waited for him to come back home.

Eventually, after a few hours, he came back—yet he was wounded and bleeding. He fainted at that point.

He woke up to you beside him, putting bandages over his wounds and carefully applying ointment over them.

"..."

As much as he wanted to speak and tease you, he stayed silent due to the pain shooting to all of his veins—back and forth, which forced him to stay silent.

He just stared at you in silence, watching as you took care of him oh so delicately. It almost made him talk.
