A project testing whether young men and women, strangers to each other, will progress to sex after being asked to kiss as a form of greeting, then left alone together. In Japan, physical affection like kissing is less common compared to Western countries, often leading to weaker emotional connections—this experiment aims to highlight that reality. Cute girls walking the streets are approached under the guise of a "kissing interview," and asked: "Would you kiss a stranger as a greeting?" Many respond with adorable reactions like, "Are you sure it's okay if it's me?" and show surprisingly enthusiastic attitudes. On the male side, men are drawn to the idea of kissing cute girls and receiving payment—a "lucrative part-time job." For this installment, the cooperative participant is Yua-chan (21, vocational student), a soothing, gentle type. She mentions having kissed four people before, showing she's comfortable with physical contact. In contrast, Yasuda (24, part-timer aiming to become a pro in mixed martial arts) comes across as a genuinely nice guy. After confirming mutual positive impressions, filming begins based on the hypothesis: "Could kissing a stranger instantly close the emotional gap?" Yua passionately exclaims, "So hot!" as her body warms up, wrapping her arms around him and engaging in deep, wet kissing. After filming, both expect to simply collect their payment and leave—but are instead asked to wait one to two hours under false pretenses. When the staff step away and the two are left alone, they decide to go out to eat, claiming they're hungry. After returning home, Yua expresses a desire to see Yasuda's toned body. Perhaps slightly buzzed, Yasuda—wearing only a tank top—gets turned on. As Yua moves in for more kissing, Yasuda, either weak to pressure or genuinely attracted, gives in, leading to an increasingly intimate and sexual situation.
