NONAME:
I have the whole ass list for that but in general I dislike those Kpop Idols turned actors/actresses....Don't come @me ..Just because they acted ( It is rather blank stares , smile, laughs, cries )in few of their MVs for split seconds.. they think they are actor now...leave that job for actors/actresses...Many deserving actors and actresses have to manage being supporting cast just because some Idols thought "acting is their cup of Tea". Their dumb fan hypes them and bring ratings which in turn makes dramamakers to bring them more....
baek in Scarlet Heart acted pretty decent ;-;
Besides, this is market, and names are brands, known brands, sell more, that's the way world works
