Kaoru arrives at Rei's apartment and slaps and yells at her for her masochistic devotion to Fukiko. She reveals that Rei's bracelet was given to her by Fukiko; she rips it off her wrist and tries to throw it out the window into the river, revealing a deep scar on Rei's wrist. Kaoru is forced to stop when Rei starts throwing knives at her, and Rei takes her bracelet back. Terrified, Nanako wonders whether or not Rei's scar was the result of a suicide attempt. Fukiko calls her to ask why she didn't return to the study group, and Nanako makes up a reasonable excuse. Fukiko pretends to believe her but correctly suspects the truth. She orders Nanako the next day at school not to get too close to Rei. Later, Nanako overhears Kaoru confronting Fukiko over what she'd done to Rei.
