More dramas like Deep in my heart?

i've been watching it lately. I really like it, usually I find myself waiting for the drama to end while watching, but this one is an exception. Any more dramas like it?

I also watched Burning Ice and enjoyed it a lot.

 Haeju:

Haven't seen Deep in my heart (yet) but here are some chinese mainland crime shows I greatly enjoyed: Day and Night, Original Sin, Medical Examiner dr Qin. They aren't the same as Burning Ice, but they have grey characters (you will keep wondering who's the good guy and who's the bad guy, especially in two first ones) + thrilling plot 

Those sound really interesting! I'll check them out!
