This is the love history of childhood sweethearts Cheng Zhixing, the "school idol" of Jingcheng Middle School, and Xia Heyi, the "last" student. The god of learning is a cooling machine to the outside world, but he is venomous and protective of his neighbours. He keeps her "idiot stickers" as a treasure, scolds her for being stupid and stays up late to correct wrong questions; the academic scumbag has a strange brain and loves to draw comics. He remembers his little habit of being afraid of the dark and allergic, and even though he thinks he is troublesome, he secretly stuffs comics into his face when he fails in the competition. Transfer students to stir up trouble? The scholar-gods are jealous of others, and they are so naive that they rush to give lectures and declare their sovereignty late at night. From daily cheating on each other to blushing confessions, from answering questions together to agreeing to test in the same city, the two wrote a sweet and funny "Instructions for Idiot Couples" for their youth.
