Royal Sister Returns (2017)

In both these chinese dramas, ML and female lead though they like each other, the ML lead marries the second female lead as they were dying. Then go back to the main female lead.

-Strong female lead
-Powerful background
-Rich families
-Business clashes
-drama
-comedy
-romance between 2 rich heirs of second generations

- FL has strong family background but choses to abandon it
-FL starts working for ML
-both are comedies, although I found Royal Sister Returns to be more comedic (maybe partially bc of good chemistry)
- There is a past connecting the ML and FL and their families
-Sm:)e has a more light hearted ending
