Mathematics genius Shen Juan is aloof and arrogant. He is the flower of the high mountains that the whole school dare not desecrate. The new student Lin Zhi seems to be well-behaved and innocent, but in fact he is pretending to avoid the attention of his family. Everyone thought that Shen Juan had Bai Yueguang in his heart and that Lin Zhi, who was obsessed with him, was destined to be his substitute. Until one day, he was explaining the IMO finale question live, and the camera accidentally glanced at the desk - pressed under the glass plate was actually a mugshot of Lin Zhi wearing ugly glasses and eating buns when he was in junior high school. The whole school was in shock, and Lin Zhi was also confused: "Wait... Is that Bai Yueguang you have a crush on, is it me?" But Shen Juan just pressed her against the wall and said in a low voice: "It's not Bai Yueguang, it's Cinnabar Moles. The only person I wanted to monopolize in my entire youth."
