Boyfriend's passive-aggressive behavior, she turns the tables and makes him her backup option.

[Ruthless tactics + fierce competition + poaching each other's partners + a nightmare of chasing after one's wife]
Si Nian was obtained by Xie Jingyao through a struggle and by poaching from his brother.
Everyone says that Si Nian is very capable, able to make Young Master Xie resort to any means to become a mistress for love.
But no one knows that five years ago, when Si Nian was deeply in love with Xie Jingyao, she took a fatal shot for him.
When she woke up, she didn't hear any heartfelt promises, but rather his sarcastic remarks to others: "Si Nian? A woman who is unloved by her parents, she's the easiest to manipulate. Treat her well, and she'll willingly give up her life."
It turns out her life was worthless, and her love was cheap.
So Si Nian turned around and went into his brother's room.
Five years after the Cold War, they reunited at Si Nian's and his brother's wedding.
Xie Jingyao gritted his teeth in anger. It was just a cold war, and his girlfriend actually got married!
He was cursing his girlfriend for cheating on him, saying she really needed to be taught a lesson.
On the one hand, she couldn't help but reveal her scheming: "Niannian, I don't mind that you have a husband, but your husband minds that you have a boyfriend. It's obvious who loves you more."
