Huh. That was a very strange, very convoluted manga. There were things I actually liked about it, despite all of the weirdness inserted here and there. I think the ending confused some people because it's so abrupt, then it's followed by a bunch of "afterwards" type stuff. The story ends with both of the original couple realizing they were both in love, and the asshole one deciding to leave everything behind. It also means the new couple stays together. Everything after that is snippets of things in the past, or personal introspection.
I actually kind of love "second love" stories with all the heartbreak that comes from the loss of a first love, then the healing that comes after with a person who actually treats you right. This is such a weird story, and it's all over the place, so I can't say that it was as satisfying as it could be, but I did appreciate seeing those themes. They're rare in yaoi. Most of the time the unhealthy relationship wins in a love triangle. The art was strange and the visuals were seriously disgusting at times, but I don't know, I think this was worth the read. I can see why a lot of people wouldn't like it, but I give it a solid B. I hope someone translates the sequel, though I worry about what might be revealed then, given how damaged everyone is in this one.
