Ep. 21: Mayaka meminta bantuan Eru untuk memperbaiki cokelat Valentine-nya sementara Houtarou menyelidiki hilangnya cokelat tersebut

During Valentine's Day of their last year of junior high, Mayaka's attempt to get Satoshi to accept her feelings fails, which Satoshi attributes on the quality of the chocolate she made. This year, she asks for Eru's help to make an even better chocolate than the last. Meanwhile, Houtarou runs into Satoshi at a city arcade, and contemplates on the fact that Satoshi seems to have lost his competitiveness from the year before. Mayaka leaves the chocolate she made in the clubroom with Eru, but it disappears after she leaves the room. Houtarou attempts to figure out who would have stolen it, but he already has an idea. Mayaka is discouraged by the loss of the chocolate and goes home; Eru runs after her. Houtarou confronts Satoshi about hiding the chocolate. Satoshi explains that, though he does want to be with Mayaka, he had stopped becoming obsessed with everything, and could not risk becoming obsessed with her. Mayaka later reveals to Eru that she knew Satoshi had taken it and that he was afraid of giving her an answer. Later that night, Eru thanks Houtarou for his help, and Satoshi calls Mayaka, telling her that he has something to speak to her about. (Source: Wikipedia)
