The Non-Existent Person

One day, Jangmi, who was lost in the woods, meets a 'Ghost' who lives in the forest. She manages to prove the existence of this 'non-existent person,' who is not of this world, and falls in love with him. However, a 'Witch' interferes with their love... Now, I, too, have become a 'non-existent person.' Can this love of ours ever be fulfilled?
