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...
So I thought I might be sick 
of eating them by now.
Ich hatte schon Angst,
ich hätte nun die Schnauze voll von Kuchen.
Así que supuse que no querría

nemmeno l'idea di mangiarne una...
Então achei que já estava
cansada de comê-los.
Я уж думала, наелась на всю жизнь.
