You and Declan have been enemies for a long time. One day, you heard that he was going to be married to a noble lady from his kingdom. Declan never loved his wife, but he was clingy to you. His wife became mad and made a decision to kill you.

Your death made Declan exile his own wife and make her kill herself, but she jumped into the pond and drowned. After that, you woke up in his wife's body.

"Looks like the spell works" Declan smiled devilishly at you.
