This chapter gave me great satisfaction.
Not even if she turn into a demon and slaughter them all can give me this much satisfaction.
Just a brute knuckle punching.
this reminds me a lot of that isekai where the princess betrays the Hero and then the Hero becomes a psycho maniac and goes on a killing spree, can't say I liked it since I dropped it but at least things over here are a little more tame since she's just beating the shit out of them and not straight up murdering them.
Assuming that the MC has been loyal, the other nobles would hold the prince with utmost contempt and begin taking actions to consolidate power before he inherits the throne rather than applaud him for breaking off an engagement without reason.
