Yun Tiancheng actually comforted Yun Shifei like that.
Yun Sisi's hand couldn't help but clench tightly.
Why? They always wanted to mold her into someone perfect and outstanding, yet they treated Yun Shifei so leniently.
Was it just because she was adopted, while Yun Shifei was their biological daughter?
Sure enough, there really was such a huge difference between being biological and being adopted.
She couldn't help but think about the recent period of time, how Yun Tiancheng and Xu Ya cared for Yun Shifei.
Always buying things for her—in the past, they would still consider her feelings and do it secretly.
But now, it seemed they didn't bother to hide it anymore.
When did it start?
Oh, right—it was that time...
When Xu Ya slapped Yun Shifei because of her.
After that, everything changed.
