Eimei, Ayane's son, was troubled by his mother's infidelity. He was deeply pained by her behavior—coming home late with men, loudly expressing pleasure without any regard for his presence. When he confided his distress to his close friend Shuta, he was shocked to learn that Shuta's mother was also involved in an affair with her real husband. This revelation only deepened Eimei's confusion. That night, he honestly confronted his mother Ayane, but she coldly brushed him off. Her firm rejection of any emotional connection with her son made Eimei begin to think differently. Wrestling with doubts about their relationship, he gradually sorted through his feelings and made a new, determined decision.
