Misumi Rei's performance as the older sister is breathtaking! The forbidden feelings that grew between urban-raised siblings during their development explode when the younger brother moves to Tokyo alone, keeping viewers glued to the screen. The climax, where the 20-year-old brother and his 2-year-older sister are handcuffed together by a neighbor with bad drinking habits and lose their freedom, leading to their first true union, is an emotional moment where decade-long suppressed emotions burst out.

Particularly impressive is the wearable camera scene in the bath. Although the image quality drops slightly, it vividly conveys the siblings' tense proximity and raw breathing, actually enhancing realism. Misumi Rei shines with her performance that blends a sisterly包容力 with a dangerous charm, expressing a wide range of emotions from natural physical contact to intense passion with the brother character. The high number of ejaculations also boosts the work's intensity, keeping viewers engaged.

Overall, the psychological portrayal of siblings wavering between daily life and the extraordinary is carefully depicted, with the dramatic tension between the frustration of blood ties and the attraction as opposites highly commendable. In the final scene, the深情演出 where decade-old feelings dissolve like lukewarm water made me watch intently. Worth seeing even for non-fans of Misumi Rei!
