He and she were childhood sweethearts. He met her under the White Star Spirit Tree. At that time, he was scolded by his father and sadly ran to that quiet place to find his brother. And she is the long-term guardian there. Their friendship started from then on. She has always been touched because he is willing to stay close to her for warmth, and they need and depend on each other. Such a kindness made her vow to follow him for the rest of her life. I just didn't expect their lives to be so long. Long enough to create a distance between their hearts, just because they are each other's nightmare that they can't let go of.
