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.

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.

Souta is given the task of reporting his family's activities to Otouru Minegishi, Kazue's ex-husband and an employee of his mother who has an annoyingly masochistic behavior. The next day, Souta has to deal with poor eyesight after his glasses break because of Aoi punching him with Daisy. while Hiroomi tries to encourage Jun to ask Kyouko out for a drink.

Realizing that he and Yachiyo both have the same day off, Jun finally finds the courage to ask her out for drinks. Meanwhile, Yamada devises multiple plans to get Sota to pet her again.

As Kyōko remains spaced out over the previous day's events, Popura tries to act more reliable to fill in for her, while Mitsuki tests Jun to see how compatible he is with Yachiyo. Meanwhile, Sōta is bewildered over suddenly finding Mahiru to be cute, outright denying Kirio's suggestion that he might be in love with her. While trying to compliment Mahiru on how much she's improved with her anthrophobia, Sōta inadvertently upsets her by suggesting she find someone else to fall in love with.

With Aoi's situation resolved, Sōta continues to be in denial over his feelings for Mahiru. Meanwhile, having finally learned Yachiyo's birthday, Jun gives her all the presents that he hadn't had the courage to give her before. Later, Aoi gets herself a cellphone, which she attempts to use to communicate with Kikuno, while Popura becomes depressed when she believes she's gotten shorter.

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.

As Sōta stops showing up at work, Kyoko learns that he has been spending a lot more time crossdressing because of his mother. Worried she is the cause of her problem, Mahiru confronts Sōta and tells him how she thinks of her, but Shizuka catches him and forces him to quit working at Wagnaria. Learning from Kyoko that Shizuka is having Sōta crossdress until he learns to be honest about his feelings, Mahiru heads off to talk with Shizuka, having to confront each of the Takanashi sisters along the way. As Mahiru confronts Shizuka with help from Nazuna, Popura shows up and convinces Shizuka to let Sōta keep working. Afterwards, Shizuka returns to her work while Sōta and Mahiru finally confess to each other.
