The years pass by in a hurry, or they drift away, or they feel lost. Every choice and decision will bring about a fundamental turning point in life. We don't know which step of our decision is correct or happy, which step is wrong or painful, but often after experiencing many things, in a certain gap, we will vaguely hope that time can go back. Let us stay at the most innocent and true moment, let us stay at the crossroads of choice, so that we can either miss it or face ourselves with determination, laugh or shed tears. In that time, we gradually mature and grow up.
