Su Jin is a problem student who "doesn't skip classes", "doesn't fight", and "doesn't smoke". Mo Ran is good at studying, has a good temper, and has a good family background. They are in the same school as if they were in different places, one is Nanyuan and the other is Beiyuan. Students of Beiyuan: "Nanyuan are all stupid kids who are behind the times." Nanyuan students: "Beiyuan are all nerds who study hard." Su Jin is the leader of Nanyuan, and Mo Ran is the student union representative of Beiyuan. Different types of people are always attracted to each other. Su Jin hooked Mo Ran's neck, sat on Mo Ran's lap, and smiled charmingly: "Bookworm, why do you like me?" Mo Ran held her slender waist and lifted her chin. "You are a goblin, and I am just a mortal, how can I be spared?" Su Jin: "I heard that you have a childhood sweetheart?" Mo Ran: "That's just a legend." Mo Ran Angry: "You actually have three ex-boyfriends, and I don't even know about it!" Su Jin replied to her domineeringly: "You just need to know that you are my first girlfriend and my last one." Then, she kissed the arrogant lips, and then, with a shy face, Su Jin said, "Mo Ran, draw the curtain down." Finally, it is indescribable, just imagine, hehe...
