This drama craziness reminds me of the type we see in 2016 cdrama "Big Boss" (the best school cdrama for me and the only one I care about cause it never takes itself seriously)
I shall check Taxi driver then. Guy is such a baby and he already gets to play psychos characters ! But why are the dramas you mentioned not part of his filmography on MDL ?
The same "traffic actors/actresses" faces in every freaking dramas and big projects cause dramas PDs want to rely on their fandoms to earn quick money instead of to rely on good scriptwritting while scouting new talents.
