Yang Ruxin did not explicitly agree to Guan Qingyue's request and even charged twenty wen as a consultation fee when she left. Charging for medical services is natural and she felt indifferent towards Guan Danian and his wife.
Guan Danian and his wife had not expected Yang Ruxin to ask for a consultation fee, they thought... never mind, it was for the best, so they willingly paid the money.
Guan Qingshu saw Yang Ruxin out to the door.
"Xinxin, thank you..." Guan Qingshu knew that Yang Ruxin wanted to avoid any sense of personal obligation by taking the money, which left him feeling quite dejected.
