I started out thinking this anime was kind of meh, then quickly began liking it, and by the end ended up loving it. It's a 13-episode series that really knows its audience and isn't afraid to target them with fan-service (straight guys, that's your cue to move on; this isn't for you).
It's a very light boys' love story with a ton of hot guys and literally no females (though they claim there are female students). At the beginning, it's a little hard to understand why people like Keita, our protagonist, so much; his only talents seem to be luck and being really sweet. But by the end, you love him, too, so you can't really blame them.
There are other plot devices that make no sense but I ended up liking anyway, like the chairman situation, that random bear, what exactly Shunsuke does, why the biology professor can't get a better password. And there are some things that are absolutely hilarious, like the student council vs. the treasury rivalry (side note: I adore Karou and Omi, who run the treasury, and the computer hacking battle between Omi and Nakajima is genius), the twins, and how utterly devilish this anime is with innuendo.
The plot also massively improves towards the middle-to-end of the series, and you see how they've been setting it up from the beginning. I guess this anime is like a better version of Princess Princess (even sharing some seiyu!) without most of the awkwardness and with a more interesting plot. It really worked for me!
