Nan Hua was not a saint. She also didn't want to pretend to be a kind sister towards Nan Xin. Such a reputation was totally unnecessary and would only bring too much problem for her. It would be better for her to make it clear that she's a willful young lady who didn't have any good relationship with Nan Xin.
That way, she would be able to draw the line between the two of them without too much farce.
There were some shows, but it wouldn't be necessary for her to act like a caring older sister.
"Nan Xin is being schemed at and you're siding with outsiders! Do you not think of yourself as part of Nan Family?" Nan Shu Cheng yelled angrily. "Do you know what the consequences of your action are? Do you know how much face I lost because of this incident?"
He's so angry.
