It actually points out how important the environment is for good acting. You co-workers, the set, the ambiance – it's tens of times harder to act believably when you're all alone against a green screen
This is fucking scary, at this point I'd just shut myself in my room for a couple of days I mean holy fuck this low key reminds of re:zero with how the MC goes through traumatizing shit till he gets mentally broken...
Seems like extreme method acting lol but at that point if you're not fit/a stunt actor feels like it'd be better to audition for rom com type/light hearted stuff (tho even for comedies kdramas can get kinda wild/crazy)
