Near perfect male leads

new here, watched alot of dramas usually alot of the melodrama type, 
flawed male leads chase near perfect female leads

I'd like it to be different this time.. 

Any suggestions? 

I already watched
Man From Another Star and Blood but thats about it.

Thank you for the fast reply! I can finally waste my time.
while i recover from my problems XD

healer
goblin
descendants of the sun
Strong Woman Do Bong Soon 

Goblin 
D-Day (which also had the perfect development of the baddie)

F4?

My Amazing Boyfriend
My Little Princess

Someone who's good at certain fields, they are perfect because they are good at what they do in relation to the story
(E.G Blood's MC is a good doctor, calm and calculating but struggles to convey sympathy and is set in a Hospital setting thus, a near perfect lead)

So, Dramas with a male lead who is super accomplished in their chosen field but may have personality flaws:
