i don't think they did it though. that fvcking b!tch is just trying to make her feel anxious. if i were her i'd slap her right away and tell her how disgusting she is. and wtf is wrong with shuunin. he should've atleast told her about those since you'd get anxious with or without knowing.
she doesn't put a spell on guys, she puts a spell on their girlfriends. probably feels smug from sowing chaos without /technically/ doing anything wrong. honestly just tell akira, she'd go to mat for shibata any day.
