According to legend, there once was a bird with white wings and a body the same color as the sky. It was unique in the world. When others saw it, it would arouse a strong desire for possession in their hearts, and they could never let go of it. Those who possess it can learn to fly. If the man and woman who owns it truly love each other, they only need to stand next to her and recite their wishes silently in their hearts. If the two wishes are in sync with each other and are exactly the same, then no matter what they are, they can come true~~~~~~~~~~~
