Ten years ago, she was ten years old and he was twenty
His college tutor was her father;
He took her to find the way back, but he didn't want to, which made her lose her heart.
The smile as warm as the sun, the smile that had made her lost for ten years, could no longer warm anyone after seeing each other again...
However, please allow me to bring you back that smile...
Because, I still remember your smile.
