When did Mdm Kong's mouth become so venomous?

After more than half a month, Ge Chunying looked at herself in the mirror. 

She dressed herself up and no longer looked haggard.

She told Ge Chunru that he wanted to go out for a walk.

Ge Chunru was afraid that her sister would do something stupid and insisted on accompanying her.

Ge Chunying was a little annoyed, but she had to agree on the surface.

Thus, the two sisters went out in the carriage.

Ge Chunying was dressed very plainly, and she deliberately made herself look weak, like a lonely little white flower.

They went to the most bustling street in Northern City.

After they got off the carriage and walked into the street, Ge Chunying took the initiative to hold Ge Chunru's arm.

"Elder sister, let's go to the best restaurant in Northern City for a meal today. I still have more than a thousand taels of silver on me. I didn't let that lowly commoner know." She said with a bit of yearning.
