College student Tooru nervously awaits his first visit to a soapland, having made a reservation with a particular girl he's been curious about. But when the appointed time arrives, the woman who appears is none other than his mother, Nozomi. Embarrassed and wanting to flee, Tooru tries to leave, but Nozomi stops him, saying, "If you go, I'll get in trouble with the shop. Since you're here, won't you at least enjoy yourself?" Hesitant at first, Tooru gradually finds himself drawn to Nozomi's skilled touch, leading him to confront his own confusing emotions.
