Ever since being teased as kid for liking cute things, Kotaro has never enjoyed Christmas. This year his parents are going on a trip for the holiday, so in order to avoid being stuck home alone with Puniru, he tries to throw a Christmas party.

Puniru says she’ll spend the holiday with whoever brings her the cutest Christmas cake, but the offerings she gets are... interesting. When a certain someone loses their patience, she may yet get a Christmas to remember.
