I don't know how common it is to release a trailer and few episodes ahead but this is why you only release episodes til after it's all finished bc of 'divas' like him to replace (even if there was an announcement too lol)
Even with mc's confidence this is prolly gonna lead to a fight/punching if he doesn't get kicked off the agency. They should really get a diff manager and maybe he'll get a better 'contract' to not deal with an actor like him again, if not a 'top tier' actor being even more obnoxious but they can get away with it b/c theyr'e like a 30 year veteran or so XD
