But I get it, MC. You suffered. You're the victim. You're the good guy. And he is! He's the good guy! He's trying everything he could to maintain their relationship. But the author made the fiance as brainless 'heroine syndrome' character. 'It's my fate to be loved!' she said, more or less. The "affair" is her dancing and dating with other guys. Sure it probably count as cheating within setting, but exiled her in total isolation for that?? And let her (implied) died later?? It's too cruel. The plot blame the education of the grandparents. I mean, if you're a sensible parent, the best way is to send her to monatery, not mountain isolation. But yeah the Marqrave/Marquis who support MC and like him was so mad and decided to push her isolation. I can forgive this plot if the fiance cheating with important people with some conspiracy agenda whatsoever, but no she's just naive brainless girl who loves men attention. Thus Marquis daddy decided to total demotion. And the fiance's family decided to move on, and forget her. Till she died. Idk. I get it, cheating is wrong. But, like, it's not like she's cheating when they're married and embezzlement his money and killing his friends? Kind of unfair, I think?

It kinda went from meh to 100 in a heartbeat. But to be honest, the punishment doesn't really fit the crime. I mean, sure she was blatantly cheating and essentially insane with 'heroine syndrome'. But I don't think that exactly warranted a mountain exile. Indefinite house arrest or getting demoted to a commoner would've been proper punishment for her actions. Hell, Make her a commoner and promise her a guaranteed position for work... At a brothel... If she likes men so much she can go there and get F*cked all she wants.

First of it's never explained exactly how far the fiancee went with cheating on the MC. It is said that she is known as a sl*t and the fiancee herself tells the MC after their marriage that he will have to prepare rooms in their house where her lovers can live.

It is sort of heavily implied that she has slept around a lot but the only things told outright is that they have been engaged for 7 years, she refuses to go on dates with him by faking ilness and such, demands gifts and money while humiliating him in public gatherings by flirting with other men openly while at the same time easily dating and being with other men while wearing the gifts they give her and telling the MC directly about how her lovers are so much better.

Instead the story focuses on the break up and subsequent outcomes for everyone involved.

Personally the story is okey but the setting and background of the story makes it weird.

In short the story is set in a medieval setting and the kingdoms nobility is split into 3 factions the royalists, the aristocrats and the neutral.

The MC is part of a powerful noble family that is of the neutral faction while the fiancee, MC's two best friends one of whom is the fiancee's sister are powerful nobles part of the royal faction so to make the MC + family part of the royalists the MC + fiancee engagement was set up but the aristocrats to prevent this merger sent honey traps against the fiancee repeatedly which is sort of the center of the story.

What is weird here is that for the 7 yeara they were engaged the fiancee's family didn't do squat to prevent any of this from happening and instead just let the fiancee do whatever she wanted with the explanation that she's spoiled and they dote on her so even though she was doing all of this in the open and everyone pretty much knew about her playing around and the engagement with the MC was important. They don't do anything but the second the MC breaks of the engagement and the male best friend who's from a higher ranked noble family, MC + fiancee families are counts while they are a step higher as marquizes, scolds the fiancee's family.

All the lovers and honey traps instantly backs off because the fiancee's family is too powerful and everyone is scared of them... Like why is this even mentioned or part of the story? If the engagement is so important and they had the power to stop their daughter or at leats the men approaching her at any time then why didn't they do it for 7 years until the MC eventually had enough???

I also can't understand why the MC isn't even mad at them a little bit and just keeps thinking and saying it's all the fiancee's fault because of how she is. Especially after we find out that the fiancee's family is implied to have known all along as well, consented to it because they spoiled her and to some degree even seemingly shielded her and tried to hide/cover up what she was doing.
