After Zeng Li only accepted the money, he said, "There's no need to check. How can I not believe you?! During this period of time, you've spent money to buy and cook Xiao Sheng's meals every day. How much are the labor fee and grocery fees? I should pay for this."
Yu Bing took note of the grocery fees. They were friends, so the labor fees definitely couldn't be calculated. After removing the portion that she should bear, Xiao Sheng owed her 8.58 yuan.
Initially, she had planned to ask Zeng Li for money, but when she thought about how Xiao Sheng had saved Zeng Li and how Zeng Li had also helped Xiao Li, it didn't seem appropriate for her to ask Zeng Li for this money again. Hence, she rejected him. "No need. It's not much money."
Yu Bing looked calm on the surface, but she comforted herself by telling herself to treat it as buying Xiao Li a shirt.
