Popura and Jun end up catching colds due to Aoi's clumsiness, so Kyōko calls in two of her juniors, Yohei and Mitsuki Mashiba, twin siblings who don't get along. When Kyōko offers to put someone else in charge of looking after Inami, Sōta becomes upset and falls out with Inami, but Inami soon manages to build up the courage to make up with him.

Sōta becomes depressed when he discovers Nazuna has grown as tall as him and has Popura act like his little sister for the day. Mahiru becomes jealous of this and works with Hiroomi to try and get Sōta to call her cute. The next day, Kirio comes to Wagnaria to look for his sister, but finds himself coming into conflict with the men, whilst Hiroomi attempts to keep him and Aoi from meeting each other.
