In a lottery to select two members for the school festival committee, Maki draws the winning ticket, and Yu is furious when her classmates playfully treat the remaining ticket as a losing one. As the atmosphere becomes tense, Yu volunteers, but Kai draws the winning ticket, and the situation calms down. However, Kai had actually drawn the losing ticket and was lying to save face. Afterwards, at Maki's suggestion, the school festival will feature art made from empty cans, and Maki and Kai work together with their classmates to prepare.

Maki invited Kai to spend Christmas Eve together, but Kai declined, saying he had plans. There was a Christmas party being held jointly with a nearby high school on Christmas Eve, and Kai had signed up to attend with Yu and others, but Maki hadn't. In the end, they made plans to have a Christmas party just the two of them after the party, but Yu ended up joining them as well. Meanwhile, rumors spread throughout the class that Nozomi Seki from the baseball club had confessed his feelings to Yu and been rejected.
