Based on the series ending, my review focuses on certain inconsistencies. Sayaka's claim of being blackmailed by the larger character becomes questionable when considering her prior interaction with him. In an earlier scene, she discusses her sister's encounter with him and doesn't appear troubled by it. Furthermore, during a phone conversation, she seems engaged and compares his performance favorably to her current partner. This undermines the notion of blackmail, as it appears she willingly participates. While the intention of that bathroom sex scene might have been to create a shocking twist, it feels predictable due to the buildup and Sayaka's previous actions. Regrettably, the portrayalof the female protagonist leaves much to be desired. Her infidelity, including cheating on her first boyfriend with his brother and former gym coach and orchestrating a harmful situation for her sister, makes her a character that is difficult to sympathize with. Overall, Sayaka's choices and actions in the series make her an unsympathetic character, among the worst I have seen in hentai.
