We were originally two parallel lines, but we still met each other in those days. I thought we could cherish those unforgettable times for a lifetime until we grow old together. But what has the passing time given us? Let us meet again as strangers. From now on, I can only be your Xiao Luo Luo, and you can only be my Meng Chen. You said you would always be by my side to accompany me. I thought that was the most romantic promise you gave me about a lifetime of happiness, but it was always my self-righteousness. When we meet again, do you miss every bit of our past? When we were childhood sweethearts, was I unique to you? How could you abandon me? If we could go back to the day we first met, when you were still that sunny boy, and I could secretly outline your every move, word and deed through the different shades of light, would we really be able to grow old hand in hand? However, time passes quickly, where will our future go?
