Missing

After Su Xiaoxiao finished drawing the blueprint, Liu Ping returned from town.

"Are you used to living in the shop?" Su Xiaoxiao asked.

Liu Ping scratched his head. "I'm used to it! The house is very big, and there's no wind or rain. The children are all sleeping soundly."

Su Xiaoxiao said, "Then, you can live there in the future."

"Huh?" Liu Ping was stunned.

Su Xiaoxiao asked, "Are you unwilling?"

Liu Ping hurriedly waved his hand. "No, no! It's just… that… Ah…"

Su Xiaoxiao continued, "I'm not letting you stay for nothing."

Liu Ping nodded repeatedly. "Yes, yes, I should pay some rent…"

Su Xiaoxiao said, "I'll give you money."

"Huh?" Liu Ping was shocked.

Su Xiaoxiao said, "Someone has to watch the shop."

"But this… I…" Liu Ping would occasionally become incoherent.

What he wanted to say was that they would be living in such a good house for nothing and should pay rent. How could they still be paid?
