After a while, Alex eventually decided to go back to his homework, but Katherine didn't let him go.
He was forced to do it while sitting on her lap, which he didn't mind, besides the little distraction inside his head.
Page 19 was another similar question, which Alex was able to complete after thirty minutes of solving it.
With only one page yet, Alex took a short water break as he turned over to see what part the other two girls were at.
To his surprise, the other two had just started page 17, and there was still a long way to go.
Shifting his attention back to the paper at hand, Alex completed it after another half an hour of work.
"Whew, there goes the math homework." Alex lets out a sigh of relief as he puts the stack of homework back into his backpack.
"Good job, Alex. Muah! You are the best son I ever had!" Katherine declared as she kissed him on the cheek.
