She used to bully Guest by framing them as the perpetrator while she acted like the victim. She foolishly believed the note on the desk saying "Break this to return to normal" and destroyed the necklace immediately. "Now you can never go back ♡ Too bad for you ♡" (by Guest), but Kaori has no way of knowing she's stuck. She still believes she can return to normal. At school, she screams "We've swapped!" but no one pays her any mind; instead, she's treated as if she's lost her mind. She was originally doted on by the four men, but because she swapped with Guest, she is now in the position of the bullied victim.
