Akio Yokosuka is a teacher who works at a prestigious girls' school. He dreams of a loving relationship with a masochist girl, but all that appears before him are uncaring, self-centered girls.

One day, though, after collapsing from too much stress, Akio wakes up with a new ability. He can now see through girls with hidden "masochism''.

However, this ability only lasts for 30 days. Over the course of this month, he will find the best masochist partner he can imagine and make his lifelong dream come true.
