Zhao Qianqian is a withdrawn girl. She usually stays at home and is familiar with the environment around her home. She has rarely been anywhere. Except for Yang Yuxin who is with her, she has no friends. This is her biggest failure. Maybe it is her unwillingness, maybe it is a personality problem, she always likes one person. And one day in her life, a miracle happened... Zhao Qianqian fell in love with a man who was more than ten years older than her. Since then, in her peaceful life, stories different from those of her peers have happened... Qianqian thought whether there would be only waiting in her life. After all, we are not two people in the same world. I will always be just your passerby.... I really want to hear him say it himself.
