Shu and Haruka appear to have a happy marriage. Two years into their relationship, Haruka decides she wants to conceive a child with her husband and raise a family. Unfortunately for the couple, Shu suddenly becomes unable to perform in the bedroom. According to Shu's doctor, there is nothing physically wrong with him, suggesting the issue may be psychological. In fact, something hidden within Shu's mind is affecting his performance: a fetish he has only hinted at to Haruka.
