First of all, I'm wondering what on earth happened to Tsukuba Sakura's trademark delicate, beautiful art. Anyone who has read Penguin Revolution, Birthday Present or Mekakushi no Kuni would agree with me on this; her art is stunning. I was confused when I read aliyu009's comment, but then I flipped to the first page, and I was... shocked. What happened, Tsukuba-sensei?! And according to the info, this is released AFTER Penguin Revolution. Some panels are nice, but others are completely... crackers.
That said, I didn't find the story quite as bad as others have said. We're given enough background to get a feel for the main characters, and they're likeable. The scenes where the classmates were interacting with each other and their teachers, or going through the motions of daily life at school; those were fun. The actual plot was a little loose, though, and the ending quite unbelievable, albeit cute. A lot of things flew by so quickly that you're left wondering what on earth just happened.
Definitely not one of Tsukuba Sakura's better works; first time readers to her works are recommended to start with Penguin Revolution instead, although you might still enjoy this one. Massive fans should keep away to save themselves some disappointment. Don't let this review discourage you from trying it, though; this is the rambling of a disappointed fan who's been spoiled by top works from Tsukuba Sakura.
