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.

Jun takes Yachiyo to buy a cellphone, whilst Kozue takes a liking to Yohei. Meanwhile, Mitsuki becomes suspicious of Jun's familiarity with Yachiyo whilst Yamada runs away after Sōta scolds her.

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.

Staying over at Sōta's house, Aoi explains her backstory about being constantly forced to study by her mother, inevitably pointing out the reason she ran away was because Kirio ate her natto. As the other staff members try to convince Aoi to return home over the next few days, Popura asks Kirio to bring over his mother, Kikuno, who is revealed to have trouble talking with others clearly to the point that her children need a manual to understand her.

Jun finally works up the courage to confess to Yachiyo, but it doesn't go well and Yachiyo goes into hiding. After managing to find her, Jun gives a direct confession which she finally reciprocates. Afterwards, Kyoko seems to want to stop Yachiyo making parfaits for her, saying she shouldn't be tied down to her, but Jun accepts that Kyoko is a key part of the girl he fell in love with.

Aoi, curious about Sōta's delayed reactions, is tasked by Yachiyo with taking a photo of Hiroomi for an album. Meanwhile, as Sōta and Mahiru go on their date, they are interrupted by Mahiru's father, who Mahiru hits when he starts insulting Sōta, managing to work things out with him. Later, Yachiyo announces her resignation to the rest of the staff, with Sōta encouraging Popura to do her best as the next chief before being mysteriously abducted.
