An interesting story where the love triangle is well develop and the setting is also very creative due to it being set after ww2 and the people grew-up right after the war and BL featuring old people. It feels natural in the way that the characters act being realistic. Props for talking and handling homophobia in a realistic manner. The story is but like Erased since it is try to fix past mistakes to prevent a murder. The story is split between the new past and current future. The story avoid the time paradox by separating time like a branch instead. I would recommend readingthis if you are sort of sick of the yaoi power dynamic where one male is clearly the man being strong and tough while the other is more girly and weak. Granted, It does fall into the classic yaoi trap of having ever male be gay like what are odds kind of thing like in most yaoi.
