Bokutachi wa Benkyou ga Dekinai!

Synopsis

Rizu agrees to visit a university open day with Nariyuki and Sawako. Both Nariyuki and Sawako claim to be sick so Rizu can be with the other person, unintentionally leaving Rizu alone, so they both go. Nariyuki leaves Rizu with Sawako in a mathematics lecture. Rizu falls asleep, irritating the professor who challenges her to solve an equation. Nariyuki later finds the professor praising Rizu's intellect and demanding she enter his mathematics course, but Rizu refuses. Sawako leaves Nariyuki with Rizu in the psychology lecture. The professor discusses memorable events like first kisses, causing Naryuki and Rizu to remember their accidental kiss in the mountains. Rizu becomes drunk from smelling alcohol fumes from a party and cries that they kept leaving her alone and they apologise. Later Rizu and Nariyuki meet Kominami and learn High Stage is holding a board game competition to win free meals. As Rizu loves board games she becomes a maid so she can play all the rare games. Unfortunately, Rizu loses so many games she costs High Stage a fortune in free meals. Kominami and Nariyuki end up stepping in to help and Rizu scores her very first win, boosting her confidence. Unfortunately she overhears Nariyuki and Kominami discussing the cheating strategy they used and she becomes depressed. Despite this, she remains determined to study psychology so she can understand Nariyuki's feelings, but she accidentally calls him "Master", as if she were still a maid, embarrassing Nariyuki in public.
