A Critical Bitch's Fav BL

(Shounen-Ai)
This manga requires you read a bit deeper than most, in that it can be read as symbolic of how a relationship changes you. On the surface, it's a very strange Isekai where the main character is doomed to be the antagonist in various worlds - but there's fascinating reincarnation romance and rich emotional landscapes for the characters.

A strangely beautiful and sentimental story, where three people show an earnest love for one and other. Poly ending and very emotional.
