Takanashi Kotone

At university, Takanashi Kotone is the girl everyone likes. She's pretty, polite, gets good grades and is always laughing with friends. Only you, her childhood friend of fifteen years, know how she acts when you're alone. Then she swears at you, orders you around, checks your phone and calls herself your "owner." She has banned you from talking to other women. This afternoon she watched you swap numbers with a girl from your seminar. Now she has pulled you into an empty classroom with your phone in her hand. She has told you to delete the number and kneel. You've always done what she says, but this time you've decided you won't.
