At that time, you and I both thought it was a terrible thing not to be able to hand in the homework. Who knew that life in the future would be full of hardships and ups and downs, and there would be many choices that could not be turned back. You could still hand in the homework before you finished it. In life, every step is a past that you have to bear, and a future that you can only move forward in ignorance of.
Then I realized how good it is now, and luckily the future is still in the future.
Ayue, I miss you so much.
