When Sota witnesses his classmate Nao masturbating in the classroom and impulsively asks, 'Shall we do it together?', a strange relationship begins where they show each other their masturbation in the early morning school building—this setup is indeed stimulating, and the first time I watched it, I was wrapped in an extraordinary excitement. However, upon repeated viewings, the repetitive patterns become noticeable, and it's hard to deny that I got bored midway. The actress Nao is beautiful, with a voluptuous figure that fully highlights her sexiness, and her charm is outstanding. But it's regrettable that her appeal isn't fully utilized. The actor Sota doesn't fit the student role in appearance, and his acting is lackluster, undermining the overall atmosphere of the work. The actress's strengths are nearly ruined by the actor's shortcomings. Additionally, while the collaboration with the original work by Mukku Maker is a talking point, from the perspective of someone unfamiliar with the original, its charm doesn't fully come through. Overall, the concept is interesting, but the monotonous development and the mismatch with the male actor are issues, making it a work that I felt needed more variety and depth.
