The Princess Wei Young (Historical) - the Princess of a small satellite kingdom is forced to escape when her family is killed and framed for treason. She is smart, strong, resilient, and bent on getting justice for her family.
Empress Ki (Historical / Political) - the plot is complex and difficult to explain without major spoilers, but the FL is involved in action, politics, and tragic events. Warning: heavily implied rape scene. This drama is not one of my favourites, but I'm usually not a fan of tragedy / revenge plots, and it is very popular.
To a lesser extent:
I Hear Your Voice (Noona / Law / Fantasy Element) - FL gets tangled up in a murder case as a child, she becomes a lawyer, and the old case becomes relevant again. ML can read thoughts.
Witch's Romance (Noona / Office) - FL's fiancee disappeared and she became a cold workaholic.
W (Action / Fantasy) - FL is a doctor + the daughter of the author of a famous manhwa. She starts to travel between the real world and the manhwa world. After a turning point, she must take the story into her own hands in order to save herself and the ML.
Princess Agents (Historical / Action) - FL does not remember her childhood. She becomes a maid in a wealthy household and is recruited to become an intelligence agent / spy. She and the SL endure a great deal of suffering. Her strength and resolve grow throughout the drama. Warning: the drama ends with a cliffhanger.
Because this is My First Life (Slice of Life / Contract Relationship) - the FL is a drama script writer. She quits writing after an actor she worked with tried to rape her. Later on, she meets a supportive entertainment company female executive, and finds the courage to file charges against the perp and to start writing again. The FL doesn't change drastically. She remains a thoughtful, quiet person, but she has an inner strength throughout, and gains confidence as the drama develops. Plus the jerk gets what he deserves.
In Cheongdamdong Alice, the female lead starts off as a "Candy girl" type, hardworking, pure and selfless (though she is strong and doesn't let herself be bullied). Then pretty early on in the series a few things happen to her that makes her take a 180 on her personality and she decides to not be a good girl anymore. I felt like there was a lot of growth in this drama for a lot of people even some minor characters. Also a nice twist on the "golddigger" trope.
