Yan Xinxin was stunned by Mu Shaoqian's act of fiercely grabbing Mu Qianshui by the neck at this moment.
Even though Mu Shaoqian deeply cared for Mu Qianyuan, no matter what, Mu Qianshui had been the sister he doted on for so many years. How could he lash out at her because of just a few words from Yan Xinxin?
And yet, what truly shocked her was what Mu Shaoqian had just said!
Mu Qianshui wasn't actually Mu Shaoqian's biological sister!
She was an orphan adopted by the Mu family from an orphanage!
She wasn't Yan Xinxin's biological sister either!
So, so that's why she could be so cold-blooded back then, watching her die without lifting a finger!
So, the reason behind Mu Shaoqian's sudden change was that he'd discovered the truth about Mu Qianshui not being his biological sister!
Yan Xinxin suddenly felt a stinging pressure in her eyes.
She never thought she'd learn such a truth at this moment...
"Brother..."
