The biggest loss IMO is Taekjoo’s internal narration. In the novel you get much more of his fear, confusion and paranoia while he's trapped on the island. You can actually feel how terrifying it is for him to realize that he isn't just being held by Zhenya anymore—now there are other people on the island who are actively trying to find/kill him. The manhwa obviously can't fit all of those thoughts in, so a lot of that psychological tension disappears.

Crying bcz they've totally ruined the beauty of the novel.. cutting details, rushing the whole story which is making readers confused.. ruined the depths of emotions, feelings.. this is totally failure..they just turned a legendary novel into some mid level story.. every time a new chapter drops,i cry out of frustration like wtf is this actually!
