Anybody knows why Daddy is so mad?
I don't think it's just because of work.
A few options come to mind:
-He's been editing the Edd x Lancer shots and is jealous/mad/frustrated with that and or can't even edit a satisfying movie from it.
-He's pissed whoever he's waiting for isn't showing (maybe someone related to the actual proper movie script he's making)
-He's annoyed that Edd's there, not with him, but instead with what he sees as homophobic douchebags.
Kyaaaa Junseo so handsome. My heart is so weak for you. ε=ε=(ノ≧∇≦)ノ
