She was a fish in a fish tank.
Fish, "every 7 seconds, will say goodbye to you."
In those 7 seconds, she only belongs to you, so she is called Yu Qi.
She never remembers you, but you always remember her.
Later,
The fish is no longer amnesiac, she has remembered the memory.
And,
The famous capital of Huaizuo, the best place in Zhuxi.
See, turn around, "forget".
Intention: Positivity, memories
