With her dislike of Yuzu and Mei's relationship, Matsuri uses the secret photo she took at the shopping mall to blackmail Mei into fooling around with text-pal on Christmas. Meanwhile, Yuzu knows nothing of this and struggles to bake a cake for her first Christmas together with Mei. While her excitement builds, Mei comes home and breaks the news that she won't be able to join their Christmas Party due to student council work...
Oh, I'll give you a Christmas present for 
all the trouble I caused, Yuzu-chan.
Oh, ich gebe dir ein Weihnachtsgeschenk
als Entschuldigung für den ganzen Ärger, Yuzu-chan.
Ah, vou te dar um presente de Natal
pelos problemas que causei, Yuzu-chan.
И Юзу, я сделаю тебе рождественский подарок
в качестве извинения за причинённые неудобства.
