On the day they broke up, Lin Wanzhou picked up a diary in the library, with Shen Yanzhou's name written on the title page. She wanted to throw it away, but she saw the first line: "I lied to her, but I love her." Opening the diary, she discovered the shocking secret hidden by Shen Yanzhou - his family's industry was being cannibalized by his mentor Li Jingshen, and he himself was Li Jingshen's illegitimate son. In order to keep the only relic left by his mother, Shen Yanzhou was forced to use a fake betrayal to force Lin Wanzhou away. But there is also a loophole in the rules written in the diary: as long as Lin Wanzhou reads the last page of the diary in front of the whole school, Li Jingshen's conspiracy can be exposed. Lin Wanzhou decided to take advantage of this loophole, but he didn't know that Gu Beichen was secretly changing the last page of the diary, while Su Mucheng was fanning the flames, hoping to take the opportunity to retaliate against the Shen family. When Lin Wanzhou opened the diary in public in the auditorium, he found that the last page was blank - Shen Yanzhou's trust collapsed, and the whole audience was in an uproar. Li Jingshen sneered in the dark, this was the moment he had been waiting for. Whether Shen Yanzhou can regain the diary, and whether Lin Wanzhou can see through the lies, this game with the diary as the anchor has just begun.
