Overview: Masaki's younger sister Manaka sneaks into school to confront Sumika over why she rejected him. Using some pity tactics, Manaka manages to get Sumika to agree to go on a date with Masaki. Come Sunday, Masaki meets up with Sumika while cross-dressing, and Manaka follows them, using a plan to get them together. Meanwhile, Ushio gets a little worried when she cannot get into contact with Sumika. Manaka recommends they go see a romance film, but they end up watching a horror instead. Next, Sumika and Masaki have lunch, though Manaka is unable to sneak love potion into Sumika's food due to her unconvincing waitress disguise. While clothes shopping, Sumika cannot handle the fact that Masaki acts more cute and girly than herself, and she runs off only to be ambushed by a trio of creepy otaku Manaka had recruited to make Masaki look like a hero. Masaki leads them away from Sumika, but soon finds himself in trouble when they will not leave him alone even after he reveals he is a guy. At the end of the day, Masaki simply tells Manaka not to do something like that again, while Sumika checks her phone to find six voice messages from Ushio.
