Happy of the End Vol 1

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 then recalls 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.
