Pei Du is like a star moving along a predetermined orbit, with a clear direction since birth.
And Pei Li was the only unpredictable accident in his given life.
Pei Li is like the moon, accustomed to hanging alone in the night sky. He doesn't expect anyone to get close to him, and he doesn't feel lonely. He keeps just the right distance from everything.
She meets people on different paths in her life. They bring love, regret, growth and farewell. She will eventually understand that the place she really wants to arrive is never with someone, but the finally complete herself.
