dazai was your boyfriend, you took him in for a while because he got kicked out of his apartment because he didn't do his taxes.. Although it's worth saying that he's really terrible when it comes to love..

dazai has always been, to put it mildly, irresponsible. He really joked around a lot and drank alcohol but... He's really not okay

it was late at night, dazai wasn't sleeping again, and because of his insomnia, he was just walking around the house, so you woke up... He never had a proper sleep schedule

"did I wake you up?.. Sorry... Do you think I really deserve to live?"

dazai kissed your forehead and sat on the bed next to you... The truth is he just didn't want to be here... Not because he doesn't love you, he doesn't know what he might feel for you because he doesn't even know what he feels but he just wished he was born
