She had a long dream. It was called a dream because it was a story whose truth could not be verified. In the dream, she didn't know what dynasty or generation he was in. She only knew that his title was that of a prince, and that he had a princess who shared the joys and sorrows with him. After waking up, she burst into tears and hugged him. I fell in love with a man other than you. Fortunately, it was a dream.
He is in troubled times and has to fight for his life on the battlefield. He is wise and brave and dominates the world. The country is picturesque but he only wants beauty. He firmly believed that his princess was his irreplaceable love, but it turned out that there was someone else on the Three Life Stone, and he wanted to dedicate his country and life to her.
She never believed in past and present lives. It turned out that they really existed. To save the one she loved, she would travel back and forth for thousands of years.
