The Ten Deadly Sins (2016)

Both are crime show dramas, with a cold and "emotionless" male lead. Difference is that in The Ten Deadly Sins, they are all investigators and not medical examiners. This one is shorter and thus leaves less room for romantic development but that's similar to Dr. Qin.

Both are crime focussed dramas and built in the same way - this meaning you go case by case through the series. Both male leads are quite cold but do have their charisma. However, love me if you dare shows a lot more of the personal lives of our investigators and does have a romantic love line that's more present than the one in the ten deadly sins.
