Misao (Ai Mikami), who returns to Toyo Trading after four long years, happens to reunite with Ichikawa (Taiki Sato) unexpectedly on a business trip. After the reunion, Misao's love for Ichikawa is returning, even though she thought it was a thing of the past. Likewise, Ichikawa feels similarly for Misao. "I love your lip, body heat, and you", the strong desire in their hearts drives them to engage in physical relationships again. Just when Misao is worried about ending up in a relationship that only has a physical connection and lacks emotional depth, Ichikawa confesses his feelings for her.
