I believe this adaption of omnscient reader's viewpoint doesn't do the original work any justice. The way the plot has changed so much and critical plot points have been excluded. Changing swords to guns did the exact opposite of what was said in the original novel and completely changes future events/characters using swords as a main focus.
Jung Heewon becoming Kim Dokja's favourite character in TWSA just seems absolutely insane to me. It changes a MASSIVE plot point about the story of Kim Dokja and Yoo Joonghyuk's relationship. Yoo Joonghyuk was the one who helped Kim Dokja through TWSA and the fact that this has been replaced with Jung Heewon is just diabolical. Yoo Joonghyuk saved Kim Dokja not Jung Heewon.
I'm disappointed how this adaption turned out so bad and I don't understand how it could change so much from the original and I really don't think it can get worse.
