I picked up this book at a con one day, and I absolutely loved it. The first story was so realistic that it was unnerving, considering I'm a gay guy and this kind of situation does happen to homosexual men quite often. Especially the scene where Moeh was giving birth, then Hiro ran to the washroom to cry about him not being able to give Shibutami a 'perfect' happy family life. It was done so well that it brought tears to my eyes.
The third one with an older brother figure was pretty cute in my opinion. Even though I usually end up rooting for the third wheel, since they are more than often the nicer guy, the main pairing was really cute in its own right. The insecurities, the uncertainties, I was digging it. It felt like the story was being told through the eyes of a middle schooler, so pure and innocent.
The art style, on the other hand, might be something that people might not like. Personally, I don't have anything against this style, but some of my friends prefer cleaner, more bishonen style. This one is not. The boys are boys, even though most of the time they appear younger than they are, but there was no long haired pretty boy. Thank god. I hate long haired dudes.
If you are interested in a realistic story line, however still light-hearted and not dark and depressing, you definitely should have a look at this manga.
