And yet... her heart skips several beats while it's all happening! One day, on her way home, Satsuki comes across a guy, Subaru, who is caught in a bad situation with another woman. Satsuki helps Subaru out, and the two of them become friends. She soon finds out that, when other women get too close to Subaru, they always end up being unable to control their desire for him. But, for some reason, Satsuki seems to be the exception to the rule!
