An adaptation based on Chapter 8 of the manga Otome Dori. While the first episode adapts chapter 8, the second episode features original content. Preparations for the cultural festival have begun. As president and vice president of the student council, as well as a couple, Reiko and Shintaro are tasked with overseeing the preparations together. While browsing the campus, they encounter a fellow student who asks them to sample the drink he is making for the festival. Suddenly, and without knowing why, Reiko begins to feel aroused and decides to take Shintaro into a classroom set up as a dark maze. Shortly after entering, the two are separated. When they reunite, Reiko finds herself unable to control her urges and allows Shintaro to help release her sexual desires, only to discover that it was not him who found her; Shintaro had already left the room. Shintaro has noticed that Reiko has been acting strangely after the incident he knows nothing about and decides to consult Misaki, another member of the student council, for help. She suspects Reiko is tired from the preparation work for the cultural festival, and the two decide that they should all take a trip to an amusement park. On the day of the trip, Shintaro and Reiko meet up, but Misaki is nowhere to be found. Reiko suddenly receives an email on her phone. She lets out a shocked expression as she looks at the image she received: an image of what has happened to Misaki.
