Stay Away from Me, Male Lead

Female Lead: Stay away from me. Male Supporting Lead: Why? Female Lead: Because the female lead is on her way... When the male supporting lead falls for the female supporting lead, when I fall for you, I realize that no one is born to be a supporting character in someone else's love story. Everyone has a one-of-a-kind love of their own. Su Qin once read a modern romance novel. She couldn't remember the plot, only the male and female leads. But when she opened her eyes, she discovered she'd become the story's biggest sacrificial female supporting character. What was she supposed to do? On her first day after transmigrating, Su Qin set herself four guiding principles: 1. Never stir up trouble. Make being an extra my life's mission. 2. Never pick a fight with the male or female lead. 3. Make friends wherever possible, especially with the story's main characters. 4. Save money and live a good life. And so, in this ridiculous, over-the-top story, Su Qin lived an ordinary life of her own, working hard and saving money. But, Male Supporting Lead, wasn't it the female lead you liked? Stay away from me...
