Rewatching Sungkyungkwan Scandal

[ofs1992]

and i am now so dissatisfied with Yoo Chun's acting. The first time i watched it i was quite enamored with him but now and after i have also watched Rooftop Prince it's quite a revelation. His acting is ah hum yaaaawn in my new opinion. My mind is full of what if this actor played this character although no specific actor can come to mind since i don't really take notice of actors and their names too much.

How could Yoo Chun play 2 different characters in the same way??? o.O
