what excuse does Yuki made? He made it clear that he is gay, and wanted a divorce. But it was Misaki and Ina trying to keep this relationship one way or another.
I think you don't know how adjectives works
he cheated first i guess? he could come out as gay to misaki before cheating? he hurts her eventho he respects her as "person" he doesn love her anymore. all 3 people have their own mistakes so i dont think yuki is innocent
non of them are
basically the story is about an indecisive spineless pathetic excuse of a man, a home wrecking f@g, a clown of a woman
