69: Itsuwari no Hohoe

Midori Aoi is a reserved, high-achieving student known for her modest demeanor and constant smile—a carefully cultivated expression she has worked tirelessly to perfect. Universally adored by both male and female classmates, she enjoys the blissful reward of being loved by everyone around her. However, her flawless facade shatters when an unexpected mistake on a recent exam causes her grades to plummet drastically from their usual top standing. Desperate to salvage her reputation and find a way out of this crisis, Midori sets her sights on her homeroom teacher, Izumi Kuwabara, who carries a widespread reputation as a slacker. What begins as a calculated attempt to manipulate an easy target quickly spirals out of control when Izumi proves far more formidable than Midori ever anticipated. Pushed into a corner, Midori resorts to blackmail, revealing compromising footage on her phone: a video of Izumi’s fiancée, Maho Yoshimura, engaged in intimate acts with multiple students. Instead of backing down, Izumi seizes control of the situation, dragging Midori into a dangerous, physical confrontation. Stripped of her leverage and left entirely vulnerable, Midori realizes the full gravity of her blunder as she endures a painful and forceful encounter that leaves her completely at her teacher's mercy.
