I disagree with the previous reviewers.
The first story was supposed tp be good, but there were so many problems that it kind of ruined it.
First of all, it's difficult to follow the order of events and, hadn't I read the description here, I wouldn't understand it. Even having read it, it's still very confusing to know how Ayamoji and Kintarou met again. Why? If Ayamoji repeated grades to get away from Kintarou, why did he went to find him again? And if he wanted revenge, why wait so long? It doesn't make sense.
While the sex scene in the first story is really, really sexy, there were disappointing issues that came along the story. What disappointed me the most was how much potential this story had and the fact that it didn't use it. Their relationship was clearly a love/hate one, and yet the author doesn't explore it at all, and the solution comes very simply.
Though Kintarou's feelings were more believable than Ayamoji's, even he should've struggled a little. It seemed rushed and when they met again as adults, it was even worse. They hadn't seen each other for five years and then suddenly it was all okay? They didn't even talk. The problem with this was that it frustrated me a lot, because it didn't use its potential.
The second - and main - story doesn't even give me reason to comment. It's exactly as everything else seen before. Cliché, not innovative at all and totally common yaoi. It's not that it's bad, but it isn't any good either. The only reason for its existence seems to be to explain the first story, otherwise it would be totally pointless. Then again, it seems out of order, being the first story Ayamoji and Kintarou's. It should be after the main story, not its introduction.
Over all, I think Gou-sensei totally got it wrong. Instead of focusing on the interesting story, she made it real quick and turned the reader's eye to a story so "yeah, right" it's even boring.
