I knew about it since I watched the survival show Idol Producer and I just thought wow things really worked differently there.... although I have an earlier memory of getting into c-ent through Taiwan/TVB dramas but that was all? But getting deep into digging the c-ent lore as an adult is a whole other experience because I am into fashion and it is the fashion in c-ent that wow me the most. I don't watch much dramas these days but I like paying attention to the fashion of c-ent
