Mamoru-kun and Ayako-san just got back from their winter trip and it is almost Valentines Day — this holiday in Japan is were the women give chocolate to the man they like—, but Ayako-san is acting weird while with Mamoru-kun. The Student Council is having a contest to see which of the female student council members can get Mamoru-kun's heart to beat the fastest. Abiko-senpai receives an email and it says that he can win Ayako-san's heart. Mamoru-kun and the Student Council President receive a bunch of chocolate. After Emelenzia-san gives Mamoru-kun her chocolate, Ayako-san tells Mamoru-kun and Emelenzia-san is acting like she is serious. Emelenzia-san then confesses to Mamoru-kun with Ayako-san standing there. What is going to happen next?
