5 things you love about me (so please remember me)

"Then, give me that 1 thing left that can make me remember you, Dazai. You said I can remember you by telling me those 5 things I love about you, now there's only one left. Tell me about it then. What is it? What the fuck is it? Those 4 others you gave me, it doesn't ring a bell and honestly, I don't even know if what you're telling me is true. I don't remember anything. I want to remember and I tried. I just fucking can't"

Dazai, calm and collected Dazai, just stood there on the verge of crying. He doesn't respond, just eyeing the suitcase by the redhead's side.

Chuuya took a deep breath and approached the door, looking at Dazai one last time, "I have to do this. I-"

"I'm Osamu"

"-"

"and you love me simply because I'm Dazai Osamu"

Or a BSD amnesia fic because why not?
