In her previous life, Lu Yitang loved Huo Zheng. She schemed every which way but couldn't get so much as a glance from him away from Chu Fangyu. Instead, she became the "vicious female rival" in their love story.
Reborn, she decides to stay away from Chu Fangyu and let her and those men fight over each other, while she makes herself beautiful and rich.
In his previous life, Fang Shaoyou was left disabled after taking the hit in a car accident meant for Chu Fangyu. All he could do was quietly wish her and Huo Zheng well.
Later, he learned that he'd protected the wrong person.
Reborn, he just wants to get away from those idiots before his own brain turns to mush, and find someone who deserves to be cherished.
Later, the two meet---
Lu Yitang: "Hey? Aren't you that tragic male supporting character who broke his leg for the heroine?"
Fang Shaoyou: "Huh? Aren't you that vicious female rival who kept trying to get herself killed?"
Lu Yitang: "Ha, men. Why aren't you orbiting the heroine anymore?"
Fang Shaoyou: "Ha, women. Why aren't you trying to get yourself killed anymore?"
Lu Yitang: "I was reborn."
Fang Shaoyou: "What a coincidence. I was reborn too."
Later on---
Lu Yitang: Huh? Fang Shaoyou is every bit as good as Huo Zheng, and he's way more handsome, gentle, and kind!
Fang Shaoyou: Lu Yitang isn't stupid, poisonous, and awful after all. She's far more beautiful and genuine than Chu Fangyu!
Lu Yitang & Fang Shaoyou: Our past selves really were blind and stupid.
After circling around and around, they suddenly realize that the other has been the one destined for them all along.
Fang Shaoyou gazes at the mark he's searched for across two lifetimes, and pours out all the love in his heart: "My dear, from now on, let me be the one to love you!"
P.S. In their previous lives, a twist of fate led the leads to be "blind" and protect the wrong people. Reborn, they open their eyes and find the right ones.
