While out shopping for some more cream, Kyouko and Yachiyo end up meeting Otoo's long lost wife, Haruna. As Yachiyo debates whether to tell Kyouko about her, she disappears again. As Yachiyo feels guilty about it, Inami learns about Satou's one-sided crush on Yachiyo and starts feeling sorry for him, leading Souta to believe she has a crush on Satou. With some support from Satou, Yachiyo apologises to Otoo after he returns and cheers up. (Source: Wikipedia)
