in terms of picking the 'right' dramas?
I would say Park Eunbin
I don't know if she doesn it herself, or someone in agency is reviewing those offers but damn
She got praised by viewers for having a mark/scar due to really practicing playin violin for 'Do You Like Brahms?'
then she played in "The King's Affection" which had really good ratings which were rising from ep to ep
next she played in "Extraordinary Attorney Woo" which had "legendary" rise in ratings
now she played in 'Castaway Diva' which was another touching and interesting drama, and she also did something remarkable with singing the song for OST
So who would you say does similar things? I have one male actor in mind but will save it for later.
