When Su Xiaofei and Lu Qingfeng arrived at the Yun Mansion, they were just in time to see Aunty Liu with a man in his late forties, whom Su Xiaofei was familiar with. This man was called Fang Yi, and he was the VP of Public Relations and Procurement at Bluemedia, the company that her mother owned.
While her mother was a businesswoman, Yun Qingrong was aware that she didn't have the right skills to manage and deal with issues related to their artists. This is where Fang Yi came in, he was the one who oversaw and dealt with such problems, sharing and lessening the burden on Yun Qingrong's part.
In her past life, Uncle Fang was really good towards her mother. As to what kind of relationship they had, Su Xiaofei wasn't sure, but she was certain that Uncle Fang respected her mother.
