Where did Shanhe Ling express his love in the original work?

The confession was made in Chapter 16. The two of them were walking by the river, talking and then started to fight. First, Wen Kexing helped Zhou Zishu heal his wounds and detoxify him, but then he started to fight after he didn't realize they didn't agree with each other. Two people were flying like catkins, and they were fighting on a boat. Ah Xu accidentally fell into the water. Wen Kexing thought that Ah Xu was being naughty with him, so he called him on the boat, but there was no sound, so he became anxious and jumped into the water to save Ah Xu. ! As a result, Ah Xu took off her makeup and saw him as she was, so beautiful, and then confessed her love.
