The bell rang... I grabbed my schoolbag and walked towards the classroom window. I saw Y packing his schoolbag.
I knocked on the window next to Y. When I saw Y raising his head, I stretched out my hand, waved, said "goodbye" and walked towards the No. 7 School bus... I didn't think at the time whether we would see each other again after saying goodbye...
Y looked out the window and was stunned. He didn't know whether he was looking at his back after leaving, or the rare white-gold sunset, or the place where we would meet again...
Intention: To miss you means that there is no regret medicine in the world
