As far as Korea is concerned it's the other way around. Actors are considered A-list in Korea and Kang Dongwon is as big as it gets. And he's about to breakout in America. It's why it's the #1 story in Korea currently.
Whether Kpoppies like to admit it or not, idols will always be considered a level below actors in Korea.
Anyway, Kang Dongwon was under YG a long time until recently. So it's definitely possible they've known each other a while.
there’a a viral twt in korean and all koreans are on his ass in the qrts tho, bc of the huge age gap. Calling him cheap Leonardo Dicaprio and all lol.
