The Tale of Mari and Yimae

One day, Mary, the daughter of a dokkaebi (goblin) hunter, stumbles upon Yi Mae, a dokkaebi, who was trapped in a mountain and saves him. Mary runs away from her father and joins Yi Mae in the search for the dokkaebi village. However, fear begins to seep in as she ventures through the cold, dark mountains. And the value of dokkaebi's eyeballs, which are worth hundreds of gold, continues to plague her. Detecting Ma Ri's affliction, Yi Mae is willing to pull out his own eyeballs for Ma Ri.
