Every spring, begonia flowers bloom. In the sea of begonia flowers scattered all over the sky, countless lives are young and countless youth is disappearing. It seems to be telling someone something, and it seems to be recalling a past... Youth, the color of a dream, contains too much, or dreams, or love, or the past that only you can understand! No matter how the world changes, I hope you will keep your true heart, wait for your pure and original self, love, go out, fight, and harvest the past that belongs to you...
