nahh!! director not really a good person actually
wait bestie what do you mean? is that a spoiler?
SPOILER!!
so basically beomi and jay(director) were a bestfriend back than when they study abroad. so jay dream want to become a good professional actor, but his acting not really good. and beomi was suppose to become a model actually good at acting. so jay got jealous about it. and he thought its unfair for him because beomi literally has everything that he wanted (wanted my arsee!!!). okay before they goes to study abroad, jay family never like him to study art(become a actor). but beomi father help him and send him to study abroad together with beomi as a spy for him to watch his son behaviour something like that(every single activities that beomi involved must be tell the father). beomi and his father doesn't really have a good relationship (basically a stranger even tho they are father and son by blood ☠☠☠). when beomi know about it, he feel betrayed because he really thought jay was one and only friends that he can depand and never betrayed him.
p/s: sorry and i hope u can understand my english!!
Rooting for the director? I dunno.
