What is love, no one will understand, why does it move, no one knows. What's the unexpected crossing? What's it like to meet him? What's it like to close the way back? Can you find love here, He will fall in love with himself. No, the arrangement in the sky is wonderful. When two hearts are tightly linked, what will appear? No one will know? Will tragedy still happen? Can it last forever? Is reincarnation really what they think?
