Zhao Yiran has never liked chasing, just like her life creed: I am lucky if I get it, and my life is if I lose it. But when dealing with Shen Mo, she gave up her creed and learned to chase and fight. But later, she understood another truth: if it's not yours, you can't catch it.
Zhao Yiran: Goodbye, Mr. Shen.
Shen Mo: Zhao Yiran, what should I do if I can't let go.
