------------------------
What happens when Dazai out of nowhere shows up in chuuya's apartment after 4 years of being gone and leaving Without a trace or a call? Will chuuya welcome him back? or will he kick him out? Come and find out!

Little sneak peek:
"The room was dimly lit, the scent of Romanée-Conti and the wine mingling with the faint smell of cinnamon. Dazai sat by the window, his back to the door, staring out into the night as though waiting for something-or maybe, as though he didn't expect anyone to come for him at all."

DIFFERENT AU:
This contains a different AU from the original anime. In this one chuuya and Dazai got engaged before he left the mafia, and chuuya knows why Dazai left but he's just angry because he left without saying anything. Either from that everything is the same.
