This article focuses on how four teenagers with strong friendships find the best happiness one by one. "Because you are Lin Youshan, so no matter how impatient I am, I will stand still and wait for you to come back. I will not run away or make a fuss. I just hope that you can come back to me safely after you have had enough fun." From the moment Lin Youshan started to follow He Yixiao and clamored to be together, He Yixiao should have understood that this woman would stay with him for life, even if she no longer stood where she was, even if she no longer came back properly.
At that time, Chen Yunmo would still laugh at He Yixiao's infatuation, but in the next second of his life, he met a girl named Nuan Nuan. He knew very well that he was the teacher and she was the student, but he still had to let her fall into his arms step by step, quoting He Yixiao's words, just because her name was Nuannuan.
