Like the other comments, I too despise love triangles. Realistically, yes, there would be love triangles in most relationships whether you want them or not. Unfortunately, whenever most authors attempt to incorporate a love triangle into their story, the result is a mess of stupid drama and tension that makes it clear that the only reason why the triangle was added in the first place was to "give the story some dynamics" in a sense. They're rarely thought out properly, and in the end you have three characters who do nothing but be annoying (the person in the middle often is the worst case as you see nothing but constantly changing feelings for no reason).
So now we've come to this manga: a story that is itself a love triangle. I plunged in after reading the other comments about the manga, hoping to experience the same satisfaction despite the love triangle. I can happily say yes, I did. The triangle here is almost exactly how they should be written; it's nearly perfect. The relationships between the characters are played out beautifully, and the personalities of the characters definitely helped make the love triangle more tolerable (if not likeable). The love tension between everyone is clearly strong but it doesn't go out of proportion like other series, staying at a nice mellow level that keeps you interested but doesn't risk turning you away. I'm always wishing for the best for everyone, no longer am i crying out in anger "Why would you do that?!" or "Make up your mind!" towards the characters.
My only dissatisfaction is when the fourth character was introduced (spoilers oh no except not really, she's right there on the cover for this Baka-Updates page) she didn't get much exposure at all. She definitely aided in the dynamics of the relationships (and helped me because I much rather prefer love squares, good ol' even numbers) but because she came in late in a rather short series of only 9 chapters she didn't have much time to make a presence. It's a shame, I really liked watching the love square with all the different personalities running around, but the series ended too soon for me. Maybe one more volume would've done it, but in the end I think the way everything wrapped up was pretty good too.
If you enjoy love triangles, then you don't need to read my review or any of the others for that matter. You would already be reading the manga by now. If you're tired of them like I am, you will be pleasantly surprised by how good this one is. I can't recommend it enough.
