Saki Yamagishi approaches Kaori on the roof to propose friendship, learning of her no-talking rule before Yuki encourages Kaori to accept. Kaori later shares her condition, and Saki compares it to her own forgetfulness, leading them to officially become friends. On Friday, Saki invites Kaori on a date to do things she always wanted with a friend, while Yuki and Shogo watch enviously. Saki shares her past bullying experience, moving Kaori to tears over their bond. By Monday, Kaori forgets Saki again, but prompts help her recall fragments of their time together. The interaction improves when joined by Saki’s friends, Maiko Serizawa and Ai Nishimura. As the day ends, Kaori smiles at Yuki, suggesting her memories are slowly returning.
