We are ignorant, so we are young. We are young, so we yearn for it. The years of youth are like quicksand between fingers. A light-year can change into a moment. Before we have time to enjoy it, the past is already waving to us. The friendship between brothers is melted into the laughter and curses day after day. Which one in the vast sea of people is my her? One day, we who are so domineering will also grow up, because we have experienced the vicissitudes of the world, only you are my myth. As promised, we will grow up together.
