Qiao Yun, seeing Qiao Xun's silent brooding, declared confidently, "I'm right."
During Qiao Se's last birthday, while chatting with him, Qiao Yun listened as he vented some frustrations.
He condemned Qiao Xun for approaching thirty yet still not ready to settle down, claiming he had someone he liked but not even a shadow of that person had emerged.
At the time, Qiao Yun had simply listened quietly, not taking the matter seriously until she deduced from the chemicals that her uncle might be involved with the organization, then she began to investigate on her own secretly.
In this age of information, as long as you have the skills, it's quite easy to search for a person's entire life on the internet.
And so Qiao Yun discovered that during university, her uncle had gone abroad for further studies and met someone named Jia Yunzhi. They were schoolmates and members of the same group, apparently with a very close relationship.
