The show starts of on the wrong foot. Sa Geum-ran, our main lead is fat.

That's it. She's fat. Point and laugh at her because apparently that means she doesn't even deserves to live.

Like Cinderella she has mother-in-law with two daughters who's whole reason for existing at all is to make her life miserable and treat her like a slave.

Via plastic surgery she transforms herself into a beauty and decides to get revenge on those that have wronged her.

The first 4 episodes try to hammer in the cinderella story. Thankfully they go easy on the fat shaming after the very episode but it's still there making it almost childish at some point... after that however it tries to be a Count de monte cristo tale but the plot's tone is a bit muddled going back and forth between the previous childish tone and the super serious Drama tone.

The actors carry this through and the music score is perfection saving it. I did feel it was padding itself to reach 21 episodes when we had a perfect ending at episode 12 or 13. It didn't need to be this long so although I did enjoy it and got invested in the characters I won't be re-watching this again any time soon.
