I keep seeing people complain about the glorification of the NSA agent even though jtbc themselves said that the character is a secret agent who’ll turn against the NSA after having seen all the horrible things they do. They included this info in their statement MONTHS ago.
If it were a documentary, sure. But this is a SERIES. It's FICTION. Anyone should be allowed to portray historical figures by blending in fiction because that's what storytelling is.
