Ning Shishen looked at the girl's shocked expression, his face wore a gentle smile, but inside he was like a stormy sea.
As expected, he guessed right.
She left when she was seven years old, even if her identity information changed, she would still celebrate her real birthday.
He smiled slightly, "It was Liu Yun who told me."
Mu Yan's eyes showed even more surprise, did Liu Yun know today was her birthday?
Her relationship with Liu Yun didn't seem to be that close.
However... she remembered there was a year in college when she participated in a competition on her birthday, could Liu Yun have been there at that time?
Being wished a happy birthday by a friend was not a bad thing, Mu Yan didn't think much of it and smiled, "Thank you, Brother Ning."
"Fortunately, Liu Yun didn't deceive me, otherwise there would have been a mix-up today, as your personal information shows your birthday has passed," Ning Shishen said seemingly unintentionally.
