Sōta's novelist sister Izumi enters a slump when she assumes he is dating Popura and will stop paying attention to her. She decides to go on a journey where she ends up meeting Mahiru who helps cheer her up. As Sōta looks after Izumi, Nazuna helps out at Wagnaria, which annoys Aoi who believes she is outshining her. After hearing about it, Nazuna puts on an act to make Aoi feel better about herself.

Whilst out shopping for some more cream, Kyōko and Yachiyo end up meeting Otoo's long lost wife, Haruna. As Yachiyo debates whether to tell Kyōko about her, she disappears again. As Yachiyo feels guilty about it, Mahiru learns about Jun's one-sided crush on Yachiyo and starts feeling sorry for him, leading Sōta to believe she has a crush on Jun. With some support from Jun, Yachiyo apologises to Otoo after he returns and cheers up.

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.

Aoi searches for her teddy bear, Daisy, only to find that Jun had just put it in her room. Later, Yachiyo overhears a conversation between Jun and Mitsuki and assumes the two are going out with each other. As Jun notices her weird behaviour, he takes some advice from Popura to put some pressure on himself to sort things out with her.

Whilst Popuar is pleased to finally reach the report sheet, Sōta is horrified by the thought of her growing taller. Whilst talking about the future, Aoi ends up turning a statement from Popura that she might have to leave Wagnaria some time in the future to a rumour that she is actually quitting, which she spreads to the other staff members. As the staff have their concerns over this, much to the annoyance of Maya the bird, Popura is confused by their weird reactions to her. After Maya helps Popura with her worries, the truth about Aoi's rumour soon comes out.
