Buddhist Princess, Come and Coax Me

She was originally the protector princess of the former dynasty. She went to the battlefield and saved the dead, but something went wrong and her country was taken away and the city was destroyed. God opened her eyes and allowed her to be reborn, and she decided to let herself live a little more freely in this life. But why did she marry the prince who was known as the King of Ghosts? During the day she pretends to be a pig and eats the tiger, and at night he pretends to be a ghost to scare people. The two of them, one white and one black, were very busy.
