The synopsis doesn't do this series justice. If you liked Taiyou no Ie or Hirunaka no Ryuusei, then you will like this one. Yuu's story--his problems as a researcher, and his feelings as a new teacher--is really just the lens to get to know three girls in his class: -- The genius who desperately wants to be "normal." -- The model dealing with her first love. -- The "loose" girl who never wants to go home. It's these stories that drive this manga, and ultimately that make it great. These three are all beautifully drawn, brilliantly written, and wonderfully developed characters. They learn, they grow, and theyall achieve a happy ending that they worked hard to find. It's some of the best character development that I've ever seen in any manga.

The other side characters are hit-and-miss. Yuu and the older male teacher are both pretty well developed (though I would have loved to have seen an epilogue chapter from Yuu's perspective that fleshed out the romance aspect a bit more.) The female otaku friend of the three main girls was always just kind of hanging around and not doing much, until the last chapter, when suddenly she seemed to have this really interesting personality. The two female teachers both played important roles, and yet were oddly lacking in character development or screen time, considering. I wish there had been more time spent on them.

Ultimately, however, the hits massively outweigh the misses. This is a great manga for anyone who likes dramatic slice of life with a little romance.
