Plot
One Monday morning, Inaba-sensei drives into school, feeling tired and grumpy. She explains to her students that she had been celebrating her birthday, but initially refuses to say her age: after needling from Sanae, she blurts out that she is twenty-six. Sanae and Amaya conclude that Inaba-sensei is single, and upset about being "left on the shelf"; they resolve to set Inaba-sensei up with a boyfriend.

Sanae and Amaya start by taking out a lonely hearts ad in Inaba-sensei's name, hoping to set her up with one of the callers. However, Inaba-sensei finds out about the ad and tricks the girls by calling them, pretending to be an interested party and arranging a meeting on Friday. When the girls try to set Inaba-sensei up for the meeting, they expose themselves as the guilty parties. That Friday, Inaba-sensei arrives at the meeting place, catches Sanae and Amaya spying on her, and warns them that she does not need help with getting into a relationship.

Undeterred, Sanae and Amaya decide to spy on Inaba-sensei over the weekend, in order to learn about her interests so they can find a suitable date for her. Sanae spies on her over Saturday, while transformed into White Star and using a spell to make herself invisible; to her annoyance, Inaba-sensei spends the whole day watching game shows and doing marking, leaving her bored. A monster attack eventually provides a welcome distraction for Sanae. On Sunday, Amaya spies on Inaba-sensei, using the same trick, and follows her on a shopping trip where she witnesses Inaba-sensei buying an (apparently) explicit yuri manga.

On Monday, Inaba-sensei once more confronts the girls about their attempts, and tells them that she is already in a relationship. Amaya, putting two and two together, realizes that Inaba-sensei is a lesbian. In private, Inaba-sensei confesses to the two girls that she is a closet lesbian, in a relationship with another woman. She reveals that her girlfriend had been the one who tipped her off about the lonely hearts ad, and that her orientation was the "secret" Hitomi had seemingly blackmailed her with during "White Star Fan Club". Feeling reassured by the girls' encouragement, that afternoon Inaba-sensei comes out to the rest of her students. Later that evening, she and her girlfriend celebrate the occasion together.
