Zeng Han, who is about to enter his thirties, encounters Shen Yujia, a high school classmate he has not seen for ten years. Shen Yujia's subversive image is very different from that in high school, which makes Zeng Han feel very scared. Zeng Han really didn't know how to define the high school classmate he called. To be honest, he didn't have much contact with Shen Yujia, and they weren't even considered acquaintances. But what Shen Yujia didn't know was that he had always occupied a subtle position in Zeng Han's heart. Of course, this fact was unknown, and even Zeng Han himself found it a bit baffling. In any case, the two reunited again ten years later, and the world had another love story.
