Maki Watase attends the campus where Professor Katsuyuki Kayama teaches. She nurses a fierce animosity toward Kayama, whom the student body widely despises, and he returns her hatred. Driven to elevate her grades, she attempts to exploit her physical allure to manipulate Kayama into compliance. When this tactic fails, she pivots decisively toward revenge.

She orchestrates a plan with three friends: Hinata, Arisa, and Sachie. Together, they spike Kayama's drink with drugs and employ a hidden camera to capture compromising images. This scheme aims to publicly disgrace the professor as retribution for his refusal. Her actions reveal a readiness to use deception and coercion, underscoring her vengeful and manipulative character.
