Nanami married her husband after a workplace romance, and they both continue to work as teachers at the same school. Everything was going smoothly, both professionally and personally, until that incident. One day, while talking to her husband in the hallway, Nanami witnesses a bullying incident involving a delinquent student, Kogure, in her class. Because Kogure is the chairman's grandson, the vice-principal warns Nanami to handle the situation discreetly. Meanwhile, Nanami's husband, Masahiro, a physical education teacher, becomes so worried about his wife that he becomes frustrated and punches Kogure, injuring him. His anger then turns towards Nanami, and she is unable to resist Kogure's lewd fingers as he reaches out to her, saying, "If you do as I say, I'll keep this a secret from the chairman."
