After the incident the previous night, both Kei and Mizuho are worried. Mizuho doesn't want her secret to be revealed, but doesn't know what to do. Kei also doesn't know what he should do or how he should explain all this to his uncle. But, what will happen when Kei and Mizuho are locked in an equipment shed overnight? Even worse, what will happen when the principle finds them?!

Mizuho and Kei get into an argument which causes Kei to meet up with Koishi later that day where she expresses her love to Kei but Kei rejects her and rushes to Mizuho before Matagu can ask her out.
