No, the choker is family tradition, completely the Dad's taste. In the novel, the MC was really impressed by her parents' relationship when she was younger and begged her Dad to collar her, too. The manga skipped that scene, though. (￣∇￣")
Nooo, in the manga there’s a mention of that! And you’re right, it’s not a world setting tradition thing, just a family tradition.
Low-key this is good?? The bondage choker thing is kinda weird but that's the world setting I guess???
