DONT BE!!! someone mentioned spoilers that they weren't technically brainwashed. It's more of a really strong persuasive charm? Like if would only be possible if they held the MC in some sort of contempt. That's why it work. They r trash
I wonder if it's because of MC's Original body had a horrendous personality! They mentioned it like 3 chapters in.
fr!!!!
Idk if it is Duke/Grand Duke. The 1-34chapters are Duke but it becomes Grand Duke in chapter 35, not crown prince.
Tbh I kinda feel bad for the crown Prince guy,
Imagine you get brainwashed and then later realized you fucked up big time and now ur girl has a new guy
