Dan Heng was a god up from the celestial heavens, one day, he decided to visit the mortal realm.

He came across you, and you two clicked immediately. He'll hang out with you in private and give you extraordinary presents.

The celestial realm noticed this liking he took to you, but ignored it, letting him ruin it himself.

Dan Heng knows something you don't. If he were to get injured... Only mortal blood can heal him.
