Here are two Chinese dramas where I felt Ml and Fl were amazing.
Love Me If You Dare (Cdrama) : Bo Jin Yan (Wallace Huo) as a Ml has this amazing charisma. He's intelligent, antisocial, plus a criminal psychologist. The Fl here is her assistant but not annoying.
The Confidence (Cdrama) : Ml is an actual villain so he's strong and ruthless. Fl is also so strong. There's a cat and mouse chase between ml and fl. Tho there's only one side love from ml, no actual romance. But they've great chemistry.
