A forbidden reunion with his ex-wife, Miike Koharu, with whom he once loved but who was supposed to have gone their separate ways. His former possessiveness is rekindled when he sees her, who was once a homely woman, now exuding a dark, mature allure after her divorce. As if recalling the warmth of each other's skin, their bodies slowly but persistently overlap. Her sorrowful moans and the nostalgic scent of soap melt his reason, and an intense time passes in which regret and lust intertwine.
