Honestly, I think its good he hasn't yet (though it might be time soon now) because I can see him turning…
His acting in bad guys 2 just revealed how much of a natural born actor he is, such a charismatic actor, he really incorporated the drama title a real bad guy, his gazes, his pain evreything, he is worth the title of a well established actor.
My heart aches evreytime i see Ji soo, such a gifted and naturally talented actor yet no director chooses him as a first lead, it's a serious waste of talent !
I don't get the hype about yoo ah in he never hit me as a good actor not even once i find his acting very overrated there are far better incredibly talented actors who deserve his fame
