There are thousands of kinds of love in this world, and the love between Aji and Yun Sang is one of them. Their love has withstood the separation of two places over the years, the fateful joke of family destruction, the miserable misery, the greedy and evil forces of darkness, and the separation of life and death from conspiracy and illness. It has remained the same as before. Their experiences may be full of ups and downs given by the storyline, but their love is always the most primitive form of love itself, never leaving and depending on each other for life and death.
