They met a thousand years ago. He was the prince and he was a fox who had practiced for nine thousand years. He is determined not to let go of him in this life, but he doesn't understand what love is. It's just fate, and they are destined not to live forever. The fox left the person he loved when he realized that he actually liked him. He ascended the throne, married and had children until his death. He promised to give him his next life, and he promised to wait for him for a thousand years. In the next life, I'm waiting for you.
