Synopsis：Traumatized by a betrayal from her ex-boyfriend, college freshman Iren develops a severe psychological aversion and trauma toward physical intimacy with men. In a desperate attempt to overcome her fears and pursue her campus crush, she accidentally stumbles upon a secret kept by the aloof and handsome Professor Owen. To her shock, Owen is also a licensed sex therapist, leading them to strike a secret pact for custom "intimacy training" lessons. Through a high-stakes game of forbidden desire and psychological power play, Owen appears strict and boundary-driven on the surface, yet secretly risks everything to protect Iren—fighting off bullies and punishing malicious rivals on campus. Under his intense guidance, Iren gradually regains her confidence and transforms into a empowered woman. However, as rumors spark and institutional pressure mounts, their strictly forbidden teacher-student boundary becomes their ultimate prison. When Professor Owen resigns and sacrifices his lifetime achievements just to shield her from the storm, the two finally break through social taboos to claim a dangerous, redeeming love in the light.
