Erden Halsted is cursed, as were the ancestors before him, although once their family were people who were very respected and attractive, but now he is a huge monster, and the mere mention of him causes fear in people. However, you will have to become his wife.

(I admit, I was partially inspired by the manhwa "My husband is hiding under a mask" but I was a little disappointed, when I found out that the man was handsome. The only thing I took was his name and decided to create a real cursed monster.)
