The "loyal dog" bamboo horse bumps into the "little pepper" Qingmei, happy enemies fall in love and kill each other, two-way secret love, friends become lovers! "The back is the most defenseless part of a person. No matter who you expose it to, it only means one thing, that is, he trusts the other person. And this so-called 'other person' until now, I have only met you." At that age where he liked to hide all his hazy thoughts, Sheng Zhixing had made a promise to Lu Xi long ago. His confession is hidden on the piece of paper with her name written on it. However, he was not the only one between the two who had looked at each other's back from a distance. Lu Xi also has a secret about him - a confession that she never had the courage to say out loud. Years later, she tells it to him again. "I... Said it was true that I wanted to be with you!" After turning in the wrong direction, fortunately, they met again. Childhood sweethearts fall in love with each other, grow up noisily, and grow old together holding hands.
