"Yes, principal, it is me. Yes, it is very important… Yes, it is their family's business. Principal, I can assure you that I will never fall behind in my studies. In fact, I have already started my revision."
The principal knew about Qiao Nan's family situation.
Unless someone passed away, the adults in the Qiao family could settle anything that happened in the family. There was no need for Qiao Nan, who was still a child, to help out.
The principal thought about it and asked Qiao Nan over the phone whether it had to do with the Zhai family.
The principal hesitated slightly after Qiao Nan's affirmative answer. He could not decide if he should approve Qiao Nan's long leave or not.
If something happened to the Zhai family and Qiao Nan was needed, Chief Zhai should have given him a call to notify him.
