She indeed used to be his wife, bought from the human trafficker by Madam Guo, intended to bring joy to the ailing Guo Feng.
During her years at the Guo Residence, she and Guo Feng grew up together, and Guo Feng was very kind to her. Guo Feng had known from his childhood that Xiaotian was the wife his mother had bought for him, but at that time, she was too young, only seeing Guo Feng as an elder brother, and she always called him brother as well.
After she turned ten, she was bought by Li Fugui, whose kindness towards her was no less than that of Guo Feng. By then, she was growing up and seemed to understand the emotions between a man and a woman, and such kindness gradually made her lose her heart.
Her heart was too small, so small that it could only hold the young master and no one else.
"I'm sorry, I can't go home with you, I am free now, no longer your wife," she said.
