Aika Nagano, a wives teacher who gets 10 times wet in the class where she can't speak.

Aika had two faces. One is the face of the table as a strict teacher. The other is the back face where you can enjoy etiquette with your students. Aika was going to enjoy the two faces in the future. However, the school's students who became more interested in their relationship with Aika came to seek a relationship. It is too dangerous for the school to end if you get caught up. Aika is shy and silent, trying hard to control the child's runaway voice and escape.
