Ryu is attending her ex-husband's memorial service and is being seen off by her friends. Among them is a former lover with whom she once had an affair. As Ryu changes into her mourning attire, the woman suddenly forces a kiss on her. Though Ryu protests, saying "No, no," she can't suppress her emotions and ends up surrendering her body. The woman then inserts a remote-controlled vibrator into her groin, and during the car ride to the memorial, their feelings intensify. This fleeting emotional turmoil becomes the catalyst that deepens the story.
