For some reason, I'm not able to reply to your other comment, so I'll just leave it here.
As you said, big names probably don't want to work with MBC, I agree with you on that, but just till that. To call the shows mediocre in my opinion is not right. Sure kbs has a problem right now with the script selections but frankly speaking, in my opinion, mbc had the best scripts this year, most of their dramas were really good. Maybe people who prefer big names may not watch them, but others who don't, all have good things to say about them. In fact, even love with flaws, which is mbc's lowest rated drama this year(probably because of all the scandals before it), was good and probably had one of the best written homosexual characters in dramas.
Also, big names do not equal to quality shows. Yes sure, they get the hype but honestly half the time, one can't help but wonder if they deserved that hype.

I've always felt that maybe what you are saying was probably the intention of the webtoon, but after the initial few chapters, I felt the focus was more on hiding her true image rather than growing from that insecurity and continued that way for a major portion of the webtoon, and in the recent chapters it's more of an ordinary love triangle than anything else. Also, not to mention, even in the webtoon, I found the backstories of the other characters more developed than the female lead, with each of them facing their own different insecurities, and I was more curious about those than the female lead because they seemed to have depth and the FL quite shallow. So, I hope that the drama gives more depth to her as compared to the other characters seeing that she is the titular character.
