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...
And I'm sure Mei would be happy too,
 because she'd have more family.
Und Mei wäre bestimmt auch
glücklich über Familienzuwachs.
Y sé que a Mei también le alegrará
tener más familia.
Y sé que a Mei también le alegrará
tener más familia.
qu’on soit beaucoup.
E più grande sarà la famiglia,
E tenho certeza que Mei ficaria
feliz também, com mais família.
Мей тоже наверняка обрадуется,
если наша семья станет больше.
