This was also changed from Little sister and Sixth sister. These two girls had gone to school and wanted to save face after they grew up. They could do anything at home, but if they went to school, she could call their names in front of their classmates.
They had to be addressed by their names instead.
"Sister Su, you're welcome. This is my job. Moreover, Su Jun is very outstanding. There are many powerful professors who want to recruit her. It's my honor to be able to benefit from her." Feng Yanze was very polite.
Su Wen was quite surprised that he called her Sister Su.
That should not be the case.
Although she was the eldest daughter of the Su family, she was actually quite young. She was a few years younger than Feng Yanze!
Besides, Feng Yanze was not Fifth sister's classmate, so he did not have to address her as Sister Su like Fifth sister's classmate.
