Liu Yun: Why did you give me sunflowers?
Gu Yu: It is a sunflower that rotates with the sun. The person who receives the flower has a heart as bright and happy as the sun, and is the best lifelong partner.
Liu Yun: Oh? Are you trying to express something to me? What does it mean?
Gu Yu: Well, it is of great significance (???)
Liu Yun: Oh, you want to say that I have a heart as bright as the sun?
Gu Yu: What I want to express is the latter sentence.
Liu Yun: Sorry, I don't understand.
Gu Yu: You are the best soul mate.
Liu Yun: What, the wind was too strong, I didn't hear it.
Gu Yu: I said, you are my partner.
Gu Yu may not have told her that the flower language of sunflowers was also what he wanted to express to her - silent love, but never leaving.
