The actress playing Rin, a former competitive swimmer, delivers an outstanding performance, with her swimsuit scenes being particularly stunning. However, the casting of the male actor raises doubts. For the role of the jealous ex-boyfriend, a more youthful appearance or a look that fits the character is necessary. From my viewing, the male actor's vibe doesn't match the role, undermining the story's realism. The plot where Rin is blackmailed and violated is tense, but the male actor's weak presence reduces the dramatic impact. At the very least, casting an actor with more 'watchable' looks or acting skills could have improved the work's quality. Overall, the actress's passionate acting and the beauty of the swimsuit scenes shine, but the inappropriate casting of the male actor is a regrettable point. As a fan, I hope future works will focus more on selecting actors that suit the roles.
