I really liked the way the author made this last chapter. We all thought that Jiwoo would win or someone would intervene, but seeing him lose and the one who spare him being Siwoo is refreshing. Maybe it doesn't make a lot of sense, but I think this decision was made because, among other things, he didn't think he would survived after killing Jiwoo, he was ready to sacrifice himself for revenge. But when he understood that Jiwoo was ready to fight till death too, Siwoo realized that he would honour his master more by being alive.
