That year, that day.
They made an agreement on the tennis court covered with sunshine.
He would wait for her at the top.
That year, that day.
They made their promise on the bank of the river with willows hanging over it.
She will wait for him here.
As time goes by, the promises made back then are gradually forgotten by them.
A certain year, a certain day.
They met by chance.
He recognized her,
She recognized him too.
But the promise made that year could no longer be fulfilled.
Who still remembers their promise that year?
Who has ever remembered that Liuli's promise?
