Any romcom with FL becomes stronger over time instead of starting as  strong FL or character progression  happens in few flashback cutscenes.  

Happy ending is must because tired of sad ending.

Few examples

Hotel king  - FL starts as a clueless girl but becomes director of the hotel after lots of failures, getting backstabbed by everyone.

Yong pal - FL put into coma for 3 years but she wakes up and kills everyone aka starts her own cemetery ?.

Birth of a Beauty - FL starts as innocent house wife. killed by her husband and his mistress but survived, get a plastic surgery, get revenge. 

Thanks

I have not seen the ones you metioned but the first leads in my recommendations sufer from low self eseem for various reasons and grow confidence as the show progresses (ie they work towards standing up for themselves or gaining independence to varying degrees)  

Money Flower

Seriously Money Flower offers leads that are full of surprises. No one truly acts how you'd think they would. The female lead included. 

Let Me Introduce Her. 

Strong Woman Do Bong Soon. Ok, hear me out: She is physically super strong, the problem is she doesn't know how to control her powers; plus, emotionally, she is very sensible. Basically, she is strong, but gets much stronger as she learns more about herself.

Watched all of them expect the Kingyo Tsuma and Joseon Psychiatrist, not a fan of history or cheating dramas.

People on the comments said it was a bad ending, is it correct?

I tried to watch it couple of times but she was/is not a good person to begin with.
