Who is Fang Rushuang? To be precise, if Qin Zhiyou hadn't met Lu Weixi first, hadn't fallen in love with Lu Weixi first, there was a high probability that Fang Rushuang would have been his love interest. Even if he had met Lu Weixi first, if she hadn't broken up with Qin Zhigu, he could have happily married Fang Rushuang.
They were indeed engaged. However, right at the cusp of their wedding, Lu Weixi and Qin Zhigu broke up and Qin Zhiyou took advantage of the chaos to win her over, leaving Fang Rushuang with nothing more than an apology.
Afterward, the Fang Family and the Bai Family moved abroad together and haven't made contact for many years.
He knew that Fang's father, who was the legal advisor of the Bai Family, had done many dishonorable things during Lu's mother's divorce lawsuit. So, the fact that Lu Weixi was able to fairly "steal" him away from Fang Rushuang wasn't entirely because he is Qin Zhisu's brother.
