A file containing private information of the moms from the kindergarten is placed in front of Yuko's door. Yuko decides not to read it, but to see for herself. The file is sent by Chihiro, who is very happy to have Yuko join their circle because she regards Yoku as a dear friend in middle-school. She mentions their past to Yuko, hoping she could share her excitement, only to find out that Yuko doesn't remember her at all. (Source: Viu)
