The Real Rich Daughter's Brothers are Crying after Her True Identity was Revealed

I was hopeful while reading this. the female lead seems like a strong female lead with a strong personality. it's a typical multi-aid secret identity Rich daughter Switched at Birth for marriage blah blah blah story but sometimes you crave that you know? you just want the drama in the face slapping. but this novel just lacks. the female lead in the male lead seem to be jumping into a physically free relationship really quickly considering they barely know each other. and why is the female lead being so sexually aggressive? initially she wasn't interested in that and was sort of like a you help me I hope you contract marriage. but the sister-in-laws and mother-in-laws treat her nicely when she met them so suddenly now she is very much determined to get pregnant to gift them a grandchild. yep. the Smart Genius multi-identally strong Fierce female lead was treated kindly by a few women for an afternoon and now is ready to throw away all of her original ideas and intentions and tried to seduce the male leads so she can get knocked up as quickly as possible and give birth for him. because that's what it boils down to for a woman. how do you repay kindness when you're a woman and you've buried into a rich family? you set aside all of your hard work and intelligence and try to breed a baby as fast as possible. because that's what a woman is worth in China apparently? or that's what a true heroine does in a story like this? anyways I stayed strong and read into chapter 40 and you could probably just ignore the whole baby making thing. because it seems like the author just uses that as a cheap excuse to incorporate really strong physical flirting really quickly. but honestly speaking I just found the whole thing stupid. it would have been better for me as a reader if the female lead just had a strong busty physical attracting towards a male lead and thought as long as we're in a contract marriage we might as well bone each other. instead of the whole no one's ever treated me kindly but these ladies treat me kindly for a few hours and even though I barely know them and barely know the male lead I might as well just put everything aside and give birth for them. that's the impression I got. and it pretty much ruins the entire story for me. furthermore the story jumps around quickly a lot. there's not a lot of world building. not that I expect much annoy 40 chapters but at least expect enough World building to get a sense of identity from the main characters? it seems like this author is trying to throw in too many details and subplots all at once and so never really gives me a chance to get attached to any of them. and don't get me wrong. I hate the novels that take 300 chapters before the male lead in the female lead even meet but this just seems lazy. so I suppose I would say it's entertaining enough for the 40 free chapters but it's not really worth spending coins on if that makes sense.
