"So you know." he whispered. "Did you heard it from Andy?" asked the man, his face bearing guilt and a conflicted emotion.
"No, we found it by chance," replied Xiao Yun and Mr. Cheng was kind enough not to ask why or how.
Instead he said, "Don't think too much. Andy too when he first knew, it was around his eighteen birthday. We didn't planned to tell him anything. We didn't want him to feel hurt after knowing he wasn't our son. But despite his sadness when he knew it, he still kept a smile that some times even I as his father felt sorry for him. He had grown up to be a good man and that is also because of you Xiao Yun."
"Me?" Xiao Yun asked, her eyes questioning why which she didn't place to word.
