"Xiao Chang, how are you?"

"Auntie, I'm fine. Don't worry."

"Should I tell them the truth?"

"You can't. Auntie, do you have enough money?"

"Yes, we have enough. The society has donated over four hundred thousand yuan. The surgery expenses are covered."

"I just transferred some money to your account. Check if you've received it."

"What are you doing? We have enough money, why are you giving me more?"

"My sister will need money for her recovery."

"Xiao Chang, is this the only way? I feel heartbroken seeing them criticize you."

"It has to be this way. Normal pleas for help wouldn't work. My sister can't wait that long. I have seen too much indifference in human nature, and I have witnessed too much kindness being exploited. To save my sister, this is the fastest way."

"I really don't know what to say. You're a stranger, yet you are helping me so much. How can I repay this immense favor?"

"There is no need to repay. Saving my sister is enough."

"But this will ruin your life."

"It doesn't matter. My life is coming to an end soon."
