I love practically all work by Mizukami Shin, so therefore, of course I enjoyed this one as well. I am just in love with her art, especially when it comes to her seme / "manly" characters. They aren't bara or anything extreme like that, but they all have just a touch of elegance and beauty mixed with a sense of sexiness. Mizukami Shin also has a talent for portraying emotions in her art as well; you can almost feel the passion the characters are experiencing during a love scene, or even feel the pain of a character losing a loved one. The only complaint I would have though, is the character design for the ukes. I understand they're in a war zone time period, but even in the modern day settings, the ukes all looked rather similar. Namely, the short, black haired ones. If they were all in one scene together, I probably wouldn't be able to differentiate between the captain of the baseball team, or Hans. Same goes for the ukes of Shin-sensei's other series as well.
The stories in this particular stories were rather cute, too. The sex scenes are steamy, and I'm definitely glad that this isn't the end of Hans and Michel; I thought their relationship in particular was rather adorable. But maybe that's just all the cuteness that Hans has to offer or the fact that it's set in a war zone. Some of the stories will probably seem rather short, but that's a given considering most of the stories in this series are oneshots. The plot for each of these stories isn't extremely deep, it's quite mild actually, so don't expect anything too serious in this series at least.
Though, not only is this series sexy and cute, it is also rather funny. Multiple scenes in this series had me chuckling, and sometimes I would laugh loud enough to stir the members of my household awake.
All in all, this series has everything for me; great art, cute plots, comedy, etc.
Don't let any of the covers direct you away from Mizukami Shin's work in general, because she is truly a great mangaka. I personally loved all the work that I've read by her, and if given the chance, I hope you enjoy her work as much as I do.
