This story's plot boggled my mind.
Kyouichi's indecisiveness and infidelity pissed me off to no end, like some other people. He always seemed to have an excuse like "I was forced to do it... I had no choice... She cornered me, blah, blah, blah." The Mangaka excused this stating that he's just a kind guy with good intentions but has a hard time of saying no...He does seem kind but because of his nature he hurt a lot of people around him
this includes: Imagase, his wife, a married woman who he was attracted to in college, his ex-girlfriend, etc.
On the other hand, Imagase creeped me out a little bit. He took advantage of Kyouichi's infidelity, using it to blackmail him so that he could "kiss" him. On a side note, I never knew kissing could be that steamy >w<. His love for Kyouichi was very obsessive, which made his character more twisted and dark. His love for him didn't make sense to me even though he did mention it was love at first sight. I just didn't think that was reason enough for him to pursue Kyouichi so ionately. But hey, is there really any reason in love?
While their character traits didn't sit well with me, I also liked them, to a certain point because they were just so realistic. And so is this story. This manga portrays two adulterated, lonely men trying to have a relationship (the "trying" part was one-sided at first but that soon changed). But the thing is, Kyouichi is -or was- not gay, and that was the suspense of the whole story: whether Kyouichi would turn gay for Imagase or not. I think the mangaka fit Kyouichi's indecisive nature very well into the story, seeing that he later has to make a choice (which he's bad at doing): sleeping with a gay man or just live life normally as a straight man.
Here's the thing though, he wasn't happy being with a woman. Yes he was content with the sex but emotionally he wasn't really in it. This was shown after he chose his ex-girlfriend and they began dating after two months. He wasn't happy, and the girl wasn't happy either.
To sum it all up, this manga is definitely worth your time, especially if you like melodramatic scenes and stuff. Although this manga wasn't very dark, just dramatic.
Yaoi isn't my preferred genre but I enjoyed it, so Yaoi fans would probably enjoy it more.
