That day, she cried. But he smiled and said, Xiaohan, it's been three years and I'm crying again, it's because of you.
That day, she cried. But he smiled and said, Yin Tian, now I am watching the stars alone again.

That day, she smiled, and her smile was overwhelming. She said, Xiaohan, come with me... To see the stars.
