All i have is respect for mc for considering and genuinely caring about the wishes of seo baek hyang ( heavenly demon ). He knows she would die but that death would gave a meaning to the life she lived. Mc cherished his master more than his personal greed, also he never resurrected her even when he was able to. If he had resurrected her one of the most powerful beings in the tower would be on his side, but mc is just built different. I was genuinely happy and sad about his choice, making such a decision in life is not an easy thing. This manhwa is a masterpiece and its novel is also very good
