The sea and the sky are two completely different scenery. If you look closely, they are blended together. However, this is just self-deception, they can never be together. Just like the sun and the moon, the stars silently guard the moon, but the sun is not even qualified to guard the moon. They cannot appear at the same moment. So, what about love? When she and he meet, do their love lines intersect, or are they parallel?
