Shuuji is a new teacher, but most of his worries don't stem from the stress at being in a new situation, but from the nightly visits of his lover Yuu – a student at the same school. And Yuu has … issues.

The new teacher, Shuuji, has a little something to worry about… His beautiful lover comes sneaking into his room night after night. The mornings can be harsh when you've been forced to have sex with your lover every night. But… That's not what's worrying him. See, his lover is actually one of his students, Yuu! As a teacher and pupil, their relationship is of course kept a secret from those around them, but what's even more dangerous is Yuu's rather odd hobby. What will be in store for them…!?
