This has a weird "taste". I like Otome Isekai a lot so I keep biting over-and-over. But this one is odd to me. I think related in what lies between in the conflict between
@saito197 and
@ojoudere. It's not the MC is being a thot or not - it's the framing of the whole thing. There's a jarring feeling in a character barely showing any sadness or grief in face of someone she should have attachments. At the same time, it is understandable as she's been hardened by her father (in a bad way because apparently he's an unempathic dick) and in a survival situation - she has no time to grieve. But then the tone and pacing sounds too comedic against such a sad situation.
But one thing I do feel quite clearly. I do feel sadness for her. Getting dumped by her fiance, her dad feeling no sympathy but just pressuring her or else, her business is being seized, apparently she has no allies. If even if she's an unreliable narrator, that she did more bullying than presented, I cannot help but feel sad for her. Essentially she is alone and has to fight. The manga would elevate a bit if it highlights that a bit rather than try to twist it into humor.
