I dropped this a while back and just reread parts of it now so I'm biased but let me tell you this:
This story doesn't particularly have seismic but it has the cliché "rich ex is now pursued by an equally rich bitch who puts down the working class MC". The MC isn't too weak but not too strong either... she often cries and crumbles down but you can't really blame her when she works hard and then fails just because some bitch wants to out her down. I don't particularly recommend this if you're looking for a strong MC. This is basically like the plot of 90% of kdrama out there.
Is there a lot of obvious and less obvious sexism in there? Is it another one of the plots with weak willed FL?
