Time Flies Under the Sun

When a familiar melody comes to your ears and a familiar scent floats in the air, will there be a moment when you feel like you have returned to the past? Those beautiful pasts that have become hazy and beautiful because of time and memories will always make you never forget them. After being born as a human being for decades, every moment will become the past. If hundreds of rivers flowed backwards, a thousand birds moved backwards, and thousands of mountains rose again, if time could be turned back, what ending would you like to give the story?
