From MangaHelpers: In a hidden school surrounded by mountains, young ladies of good families are taught everything a high class lady needs to know. They are also completely cut off from the outside world, keeping them sheltered and innocent. However, a problem has come up recently-- more and more graduates are failing to cope with the modern world after graduation. To deal with this problem, they've decided to kidnap a male commoner student, and enroll him as a student. They hope that this will be a gentle way to introduce the girls to the outside world. Kagurazaka Kimito is chosen for this dubious honor, mostly because he seems utterly average. However, the school leaders also seem to have concluded he's a homosexual with a muscle fetish. When Kimito hears that the alternative may be castration (to protect the girls' purity), he eagerly plays along with this misconception. Now he'll just have to survive the attention of many high class young ladies that are completely out of touch with the world! [tethysdust]

Spin-off that focuses on Kimito's daily life at Seikan Academy trying to teach Aika and the Commoner Club Members the world of a commoner, while dealing with mishaps and chaos that's caused by both Aika's idiocy and Kimito's tendency to tease and trick her at the worst possible moment.

From Vices and Devices:

When his interior designer mom takes off to New York for a year, Toranosuke, dorky name notwithstanding, gets sent to stay with his uncle. And it's just his luck that Ryouji is obnoxious, violent, and has the same sharp tongue as Tora's mom. Only it turns out that he's not really that bad, and maybe Tora is falling in love (with his uncle, of all people), and Ryouji has a heart of gold underneath the bellowing and violence. Except that Ryouji's pretty much the worst guy in the world to fall for: he enjoys sex more than eating, has a commitment problem, and has long since convinced himself that he's really, really straight.
