Three Actors that is always suitable to be the main lead and not as supporting actors.

There are lot of actors in the Korean entertainment. But I think there are few that will be more suitable as the main lead and not as supporting only. Maybe because we love their acting and or their looks is more than capable being the main lead.. Well for me this is my top 3.
1. Jang Hyuk 
2.Jung Kyung Ho 
3. Ji Sung

1. Gong yoo
2. Jang hyuk

ok, narrowing down on 3 would be really hard but I will give it a try:

As far as drama is concerned:

1. Ji Sung

2. Jang Hyuk

3. Jo In Sung 

--------------------------

and when it comes to movies, along with Ji Sung, I would say Lee Byung Hun and Jang Dong Gun.

 

but the truth is, even if either of them were a supporting actor they would occupy my attention as if they were the lead.  I would also add Hyun Bin and So Ji Sub.
