Happy of the End, Vol 1 by Ogeretsu Tanaka (Paperback)

Dazed and confused, Chihiro awakes on a pile of garbage with memories of wedding still fresh in his mind. When out of the blue a young man named Keito appears before him. Instantly, he thenrecalls the night he spent with this person. The booze! The hotel! The punch to his face!

Chihiro may not have a place to call home currently and Keito may not be a good person by any means, but maybe the two of them could be happy together.
