i have to say , this is one of my biggest disappointments "if not the biggest" .. the development of characters is pure shit  ... if you think of every character's doings , it makes no sense whatsoever , like Un , why did he became an assassin .. first it was he was mad at his father , then to avenge his father -_-  , and after he knew that his father killed himself and told him not to kill anyone else ..... why the F did he continue to be a Fucking assassin -_- i was hoping for a plot twist at the end .. but no it wasn't a successful plan so that he can became the leader of the assassins and dissolve the gang , it was just pure stupidity for no apparent reason ...... as for the sword saint and ga ok and sky lord ... this story is just a mess .. if Ga-ok loved sword saint why didn't she leave with him ?? .. she left him twice .. sword saint told sky lord that he "sky lord" sacrificed everything for Ga .. what everything ?? then he stayed because of her ?? and she stayed because of what .. him ?? WTF .. if she stayed because she was afraid of the gang hunting her down and killing her loved ones as she told Un ... for god's sake she is one of the gang's lords and if she left with sword saint .. who could possibly face them ?? and how would they find them to begin with ..... am i the only one who doesn't get it ?? ..... i'm very disappointed , it could have been much better .... again the development of characters is pure shit .. it left me with "what the fuck?!! - why the fuck?!! -when the fuck?!! - where the fuck?!! - how the fuck?!!" .... Overall they fucked up
