Ning Yu has been traveling with Ning Xia since she was a child.
When he met Qi Han again, he put on a frog show.
But after many years, Qi Han realized that when he met Ning Yu again, it was his heart that recognized Ning Yu before him.
That frog prince and little fish princess who is just for him.
The bohemian and playful Sun (Shou) and the calm and sullen (Go)
Ning Yu: You liked me when I was considered a girl when I was a child
Qi Han: What I like is you, regardless of gender
Purpose: True love is the common progress of both parties
