I am Cheng Xiruo. In my college life, many things happened that I found difficult to accept. When my best friend and her boyfriend stood in front of me holding hands, I used anger to cover up my sadness. When my former best friend and ex-boyfriend humiliated me in public, he was the one who showed up to help me. When I was alone and helpless, he gave me warmth and joy. It seems that he has always been by my side... But he is not my lover.
