"So, you have a problem in this chapter?" Song Xueyun asked as she saw the chapter that An Xiulan was showing her. "Actually, it's not that easy but if I explained it to you well, it won't be that tough either. However, I need both of you to not bicker and only focus on the notebook, do you get it?"
"Xueyun, you are even stricter than Yan Ge, " An Xiulan sighed.
"Is he even strict with you?" Song Xueyun rolled her eyes. "I think these days he is more happy than ever. One day, he even waved hello to me. Can you believe it?"
An Xiulan and Han Zixin didn't say anything because they had discussed how suspicious Gu Shangyan had been behaving all this time. They could spy on him but they chose to give him a benefit of the doubt.
Song Xueyun began explaining the chapter to the two best friends. It took almost four hours and now the three of them were exhausted.
