Through time, in his twenties, he still achieved nothing, and returned to the night before he graduated from elementary school. Crossing the boundaries of time and space, standing on the other side of time, facing the past that has been tearful countless times, we must regain our regrets step by step, and live a new life like a phoenix. Back to those youthful years, in fact, I just want to make life better, and then in the campus when the yellow leaves are falling, looking for the moment when I was once excited, and find the most beautiful moment when it was as bright as a meteor, but withered like a falling leaf. At that moment, maybe there is also a trace of affection in your heart, which will always linger in the bottom of your heart.
