Synopsis
Nemu, the protagonist’s cousin and girlfriend, runs away from home after a fight with her parents. Since their relationship is approved by both families, he agrees to let her stay—with one condition: they must maintain a platonic relationship until her graduation.
When he returns from a convenience store run (which Nemu refused to join), he finds her looking coldly at him while holding an adult magazine he’d borrowed from a coworker. The magazine contains explicit BDSM content featuring women in collars and restraints.
“Is it because you won’t do anything with me… that you have these kinds of tastes…? Because with me, you can only do normal sex…?”
Without a word, Nemu rummages through her bag and produces a collar, thrusting it toward him.
“Hurry! Come on, put it on me! Put the collar on my neck! Not that I want it or anything…!! Hurry! Put this collar on me… you do it! Like the women in this book, put the collar on me…!!”
Thus begins the story of Kentaro and Nemu’s days together—with a collar attached.
