Kdrama with good amount of action

Its been a long time since I watched a kdrama with a great plot, good fighting scenes and action, obviously romance is a bonus. Looking for a recommendation for kdrama’s that fall into a similar category.

A list of drama’s I have already watched and which I loved:

• K2 : Loved Ji Chang Wook in it.

• Kill it

• City Hunter

• Healer

• Man to Man

• My secret Terrius

• Descendants of the sun

P.S. I am not really good at handling drama’s with a sad endings. Would appreciate if the dramas are something similar to above mentioned list and not older than 2014.
