I actually watched this work too! The scene where the colleague's large breasts are visible through the rain-soaked shirt is absolutely stunning. The psychological portrayal of the male actor, initially resisting with 'I shouldn't' but gradually succumbing to desire, is masterful, and the sense of taboo unique to working adults is irresistible. The setting of a rainy night affair creates realism, and the intense love scenes within a loving atmosphere are sure to excite. Particularly, Haruka-chan's proactive approach and chemistry with Yuuto-kun feel natural, and visually, it's explosively charming. Although some point out immaturity in acting and sex scenes, overall, it's thoroughly enjoyable as an adult love drama where guilt and pleasure intertwine. Worth buying the DVD!
