They both have undercover police as the ML with action and romance. A Journey to Meet Love deals with finding more about the FL's parents, and Never Say Goodbye is about illegal drug trading.

The plot sounds similar. A girl is successful as a cook, but later kicked out of the palace and then becomes a physician.

Both male leads are good at fighting and are undercover (although one is a cop and the other is not). Female leads are both fierce and are strong-willed as well.

If you were a fan of A Journey to Meet Love, the City Hunter has romance, comedy and great action scenes!
