It scares me how uneducated you people are. I'm genuinely concerned by how many people are defending the top here. BDSM is built on consent, communication, and negotiated boundaries, not using someone's trauma as an excuse for violence.
The MC didn't cheat. From what was shown, he was sexually assaulted after making it clear he had a boyfriend.
Beating him, dunking his head in a toilet, throwing him out, and threatening him with more abuse isn't "dom discipline." It's abuse.
If you think that's a healthy BDSM dynamic, you seriously need to learn the difference between consensual kink and domestic violence. Do none of you stupid mother fuckers get the concept of a brat in a BDSM relationship? Do you think he meant to cheat? Obviously he didn't mean to. The author implies that he was r*ed. There's something seriously f**g wrong with you go get that checked out. Yes the rapist deserves to go to jail and f**g rot in there.
but how/what exactly does "Dom discipline" work?
