I'm honestly not a huge fan of her either. At the very start of the story her plan was to trick a man to marry her so she could leave the country and live a fairly good life with luxury, but enter the male lead and she's suddenly taking the moral high ground as if she never thought of doing it in the first place.
Its not like she would have slept with and married the other guy (forget his name) because she was in love with him. He might have been forced to marry her out of obligation too. She was doing it out of convenience. But she'll resist the ml at every turn even after it looks like she's in love with him to further the plot.
I mean ngl *looks sideways* would fuck the hot guy (づ ̄ ³ ̄)づ XD but I don't think she ever took high moral ground? its always been a grey area, I mean when she was kind it was to either get something or help her brother or somebody she cared about. I also think a lot of people forgot that right now she's still only seeing her own body's attraction to the romantic ML (she denies feeling becuz cooties lol) and she think that this whole scheme is just part of their contract.
In a way, she did take the moral high ground. He offered her luxury and she said something along the lines of I only take what I earn? Can't remember if that's the exact wording but it carries the same meaning. Because what she initially wanted was someone with money who'll marry her and take her away but since its the male lead she's acting differently. I wish the writer gave her a different motivation in the beginning or shifted it so what she does later on makes sense. Its supposed to further the romance maybe but I can't take how she acts sometimes likes she's forgotten what she set out to do in the beginning, its never even brought up again as far as I read, I stopped somewhere around ch50 and skipped to the last chap because I lost interest in the story.
I like the fact that the female lead is strong but she's getting kind of annoying. She knows she likes the ml but still denies it, kind of getting on my nerves. But im still not gonna drop this, I SHALL READ IT UNTIL THAT BOTH CONFESS THEIR LOVE and then forget about it lol. ╮( ̄▽ ̄)╭
