Dramas with "Stoic, quiet, intense male leads"- please recommend

Hi,

Just finished Boss and Me and currently watching Eternal Love (3 Lives 3 Worlds).

I really love the male leads in both dramas.

Guys, perhaps you can recommend me more of these type?  ????

It can be Korean, Chinese, Taiwanese or Japanese

Love Me If You Dare
When A Snail Falls In Love
Love o2o
Liar Game
It Started With A Kiss
From Five to Nine

stoic, quiet, intense male leads, but not necessarily any romance:
My Amazing Boyfriend
Cruel City
Rich Man, Poor Woman
Bad Guys
The Liar and His Lover (Japanese version)

Faith--it totally gave me "strong, silent and noble" male lead withdrawal syndrome lol.
