I think it's both. I think that he either fell into the body of the actor in the real world or that's him. I would HOWL if he just showed up with his historical robes like no big deal in the middle of the street. But it does look like they could be on a set.
I’m on ep 12 and I feel like nothing is happening so far just a pity fest for the ml and the fl has somehow…
But there is more to that - it's basically she has no idea how to GET OUT of the script and that she doesn't want to complete a script where the ML abuses the female and cheats on her. Which is the whole reason of why she is fighting against it. She is concerned because she doesn't feel like she can put her bias and her beliefs aside to complete the script which is why we have moments of her fighting against it but the script winning. Which we are still quite unsure of. Is the script truly working in her favor, or is there someone making sure that while she does these things to change NH that it's having her complete the path of ending up with NH WITH CHANGES?
I have to give a hand to the scriptwriter. Halfway through and she has pulled off a really strong story with some really interesting topics and layered characters hidden within the tropes and parodies. I really hope she gets another chance to deliver a fresh script from her mind. I also hope we get a really good interview or discussion with her regarding her influences and nods.
I think when NH / LSL starts accepting what she is saying and believes in it then he will start realizing that something is up. I can see this turning into some sort of Looney Tunes moment when the animation confronts the script writer, or they break the fourth wall.
She just has to get him to believe in this script thing.
I feel in the end NH is gonna be friends with CGH and probs his brother again. I don't think his brother actually hates him, he just is scared of him and is just overdramatic.
My other hope is a special where you find out all the characters peaced out of the script and are living in the real world and it leaves a cliffhanger about the way into the script and out of it and we get a part two. I want my Cinematic Universe!
Didn't someone say that this is the first in a (expected) three part series? Could you see if more CDrama actors get in on the fun? We could have a marvel universe of CDrama actors falling in and out of scripts with other stories.
In defense of both the FL and ML:For the FL:She’s a modern woman unused to the rules of this era and has no…
100% this right here. Plus, it's a comedy on something that we don't have a script already or a book out there for. Nobody knows the outcome except based on what we can infer.

Soooo I definitely see him coming to understand and them taking on the omniscient figure controling the script.
