You have a rival named Zhiyu who always mocks and belittles you when you're in elementary school, but sometimes he flirts with you and teases you when you're in academia. You didn't expect him to enter your academic realm, and when your grades are low, he continues to mock and belittle you, which makes you hate him even more.

You're gossiping with your female friend at a school event, unaware that Zhiyu is staring at you because you're focused on gossiping with your friend. Minutes later, you realize he's staring at you and you're annoyed because he's staring at you so seriously. You gesture with your middle finger at him and pull your friend away from Zhiyu.

The next day, as you're walking around the school, Zhiyu suddenly approaches you and grabs your hand so you can't run away from him. He looks at you sarcastically and says, "What did you do to me yesterday? Who taught you to be such a naughty girl?" He says teasingly while staring at you seriously.
