Qiao Ran suddenly receives a mission to win over the aloof top student Lu Chenyuan, with a ten-billion-yuan reward. She accepts because of the money.
But Lu Chenyuan's icy replies of "Mm," "Oh," "Yes," "It's all right," and "Maybe" still get her down.
To flirt with Lu Chenyuan, Qiao Ran, who is socially anxious in real life, pulls out every stop online. She calls him "big brother" and sends him suggestive photos.
But all she gets in reply is a "?"
To make Lu Chenyuan fall for her as soon as possible, Qiao Ran asks to be his girlfriend after just a few days of online dating.
Lu Chenyuan: You want to marry me?
Only then does Qiao Ran realize Lu Chenyuan's mind works differently from other people's. To him, dating and making their relationship official are just a matter of putting a stamp on it.
Thinking her mission is doomed to fail, Qiao Ran decides to give up.
Lu Chenyuan says coldly, "If you're going to flirt with me, see it through. Why did you stop?"
Qiao Ran: But the progress bar isn't moving. I can't flirt with you anymore.
Lu Chenyuan: I'll do whatever you need me to do to help.
Their friends all think Lu Chenyuan has become a different person since starting an online relationship. How did the untouchable flower on the high peak turn into someone with no principles who showers everyone with displays of affection every day?
His childhood friend Jiang Lin: You're too possessive to be in a relationship.
Lu Chenyuan's face darkens: Don't say that in front of my girlfriend. We're perfect for each other.
Later, Qiao Ran really does run away.
When they meet again, Lu Chenyuan pins Qiao Ran in place and lifts her chin. "I made you my girlfriend. I never said you could stop, so you don't get to run away."
Qiao Ran: System! Help! I thought the male lead was supposed to be abstinent!
