Aya and Yatsumura are back home, but Yatsumura asks Aya why she was being harassed by Sarina's group. She explains that everything happened when she entered room 2-B and was presented as a new student, from that first moment Sarina tried to start a conversation with Aya, but when she was shy she could not answer her, leaving a slight resentment in Sarina that was going up exponentially as various events happened at school, such as the delay she caused when she could not finish physical education classes or during the reading class where Sarina again helped her out of that situation, but Aya could not thank her so was approached in the bathroom where the harassment began. Aya feels that all this was her fault, in that Yatsumura hits her forehead and they say goodbye to go to their respective homes. Yatsumura falls on the ground weakened by the shortening of life because of the use of her stick.
