This work depicts an affair that begins with a chance reunion, and after actually watching it, I was drawn in by its intense atmosphere. The story is straightforward and clear, starting with the husband's business trip leading to a reunion with childhood friend Yuka, where they engage in passionate encounters like a couple in their first relationship, sacrificing sleep for three days—a development that is easy to follow and just right. The setup of falling into the swamp of infidelity is superb, and the tender interactions with male actor Aoi are endlessly enjoyable. Yuka's charm stands out; although she lacks in voluptuousness, her cuteness is enhanced by a seductive allure, with improved erotic techniques and sensitivity shining through. In the first half, she takes an active role in seduction, while in the latter half, she switches to being passive, showcasing a variety of reactions and expressions. This proactive role setting highlights her most attractive aspects, pairing well with the creampie specification for an optimal level of eroticism. The fleeting nature of the intense time shared between comrades with mutual feelings adds depth to the entire work.
