223 The two of us

Nian Xiaomu: "…"

The iceberg had transformed into a warm-hearted little angel—was she hallucinating?

Would he actually tell her that the cost of her meal would be deducted from her bonus after she ordered more food?

When Nian Xiaomu thought of this, she shook her head vigorously, just like a rattle-drum. "I am full, very full."

Chen Zixin, who sat at the side, had already set his mind on treating Nian Xiaomu to a meal. Confused, he scratched his head when Yu Yuehan wanted to foot the bill. "Yu Yuehan, we had agreed that this was my treat."

When Yu Yuehan heard this, he raised his eyebrows, opened his thin lips, and said, "It wouldn't be good to treat us since there were two of us."

"…"

What did "two of us" mean?

Why did this sentence seem like he was swearing on sovereignty?
