There is something wrong with sang won, I'm pretty sure he chose ji won only because she was more understanding and mature but here is the thing it's called chickening out, rather than rejecting politely he chose an easy way out.
Fl have some of the worst clients like one wants to use connection and bribes, one doesn't want to divorce even after husband infedality and another just wants to use child for social media
So far I think there is a lack of emotion in this story, life isn't just black and white it can be grey too, randomly people are falling for her and her father's side family wants to see her ruin there is no depth honestly,her meeting nice and bad people randomly doesn't makes sense
