All I Want for Love is You

To Fly With You

My Fated Boy

2nd fl are bitchy or nice?

 _sunflower_:

All I Want for Love is You : 2nd FL is annoying from the beginning to the end. 

To Fly With You : she was really good and nice in the beginning but then became annoying. 

My Fated Boy : she was annoying but you can't get mad on her as she is actually sweet but just childish. 

If you want to watch some good SFL then 

You can try Legally Romance : it has a really good SFL who actually understand the ML and FL and helped them to get together even though she liked the ML. 

My Little Happiness also has a 2nd FL, actually not one but there is 2 FL female leads -- for main lead couple (FL-ML-SML) and for second lead couple (SFL - SML - 3FL) 

No i think bitchy one add spice to the drama

What about historicals? Lots of women competing for men in the dramas. Many include the possibility that both can have him. (Seems like the men are more monogamous than the second FL). "When I am his wife, you'll only be a concubine, so learn your place."
