Meiko Koide is one of those mangakas whose works I rarely dislike, but I must say, the other reviewers are right: she was really off her game here. The two characters simply don’t fit with one another. On the one hand, we have a likeable seme who, for a shocking change, really thinks things through. If something doesn’t make sense to him, he asks questions, he looks at things from different angles; he’s rational and logical in a believable way. This is a guy who could jump off the manga page and survive just fine in the real world. On the other hand, we have a uke who is so out of touch with, well, just about everything, that there’s something ghost-like in his mannerisms and even in the way he’s drawn. It’s as if he floats through life literally and figuratively. He’s unpredictable and illogical and so incapable of even the most minor self-analysis that it’s difficult to believe in him as a character. Someone that extreme in his thinking and actions works if we’re meant to be reading him allegorically, but not if we’re meant to take him literally, and certainly not if we’re meant to take him literally as one of the leads. With this level of difference between the two, there’s no way that Ken-san and Sachi should even be in the same manga, let alone paired together as romantic partners.
Oh believe me, I get it, it’s meant to be opposites attract here: the confident Ken-san falls in love with the unconfident Sachi, and in the course of their relationship, Ken-san’s love heals Sachi’s heart, and his level-headedness helps ground the flighty Sachi, true love conquers all & etc. Which is all fine and good for the uke, but I ask you, what does the seme get out of it? Sachi is a slut and more than a few sandwiches short of a picnic basket. But unfortunately, the seme’s feelings are never adequately built up; without warning, he abruptly transitions from being unsettled by Sachi to declaring his true love forever. As the reader, you somehow get the feeling the mangaka knew deep down it would never actually work between them and so didn’t bother to try justifying them as couple. Just as the mangaka didn’t bother to try with the explanation for the uke’s past—your jaw will drop at the clichéd-ness of it.
If you’re familiar with the other mangas that feature Yuu and Jin, the guys from the pop duo Cross, then I would recommend taking a look at this manga as they do make a number of very brief (but comical!) appearances. But if you’re not a fan of those two, then I just can’t recommend this manga as it’s pretty lame.
