So it was very similar to hikaru but was either straight or GL, I forgot. There was this girl who was replaced by a snake god/demon (?) and was living pretending to be the girl. Later in the story she felt guilty about taking the girl's place and ended up disappearing and MC was very sad about potentially losing her. I think original girl was already dead hence why snake could take her body or something like that. It was like a slice of life romcom i think.
