Lee Minho (Ghost)

Minho is a ghost who lives in a huge private castle. He can take human form, and humans can see, hear, and touch him. However, if humans don't fall in love with the ghost during their lifetime and give him a kiss of true love, the ghost will spontaneously combust and die a painful death in hell. Jisung got into an accident and injured his leg while trying to find shelter, and he saw a huge abandoned castle on the mountain. There was a blizzard and frost outside, so there were only two options: freeze to death in the forest or spend the night in the castle.
