Megumi proposes a punishment game for him and the other girls want to join in. Mao proposes a nickname for Kyōya, and her and the rest of the girls decide upon "Kyoro".

On a later date Mao plays the same prank on Kyoya, which he falls into again causing him to sulk, making the girls feel bad. Kyoya sees Kirara talking with a cat. Mao finds an old TV that when booted up was playing a Tigers game which is Kirara's favorite team.

A marriage ceremony is preformed. A sweet potato vendor comes around, and the girls fight over the last one. The GJ Club discuss what they will do for the culture festival. Megumi, Mao, and Shion decide to dress up to tease Kyoya. Mori, the Amatsuka family maid, brings something Megumi forgot. Kirara and Kyoya dance, and Kyōya says something that embarrasses her.

Kyoya brushes Shion's hair. Kyoya tries to talk in a more manly fashion. Mao knits a big stocking for Santa. There isn't enough room under the kotatsu for everyone. Kyoya gets depressed when he doesn't receive any Valentine's day chocolate only for Mori to show up and give him some.

Kyoya is nowhere to be found in the club room. It seems he has taken the day off to do something with his younger sister. Furthermore, Kirara has her own younger sister, and Mao and Megumi have a third younger sister. Meanwhile, Mao suddenly invites Kyoya out, and she is clearly dressed strangely...
