Bai Yuren looked very calm, while He Zheng clearly looked like he was struggling in the chop-board, waiting for the butcher swinging the knives down.
"Ah, gege. This is my friend, He Zheng. He was in the same year as me, we were often placed in the same division." Bai Yuren said, answering Bai Yutang's question. The division Bai Yuren speaks about is the division in the hospital they sent to do their internship.
What makes Bai Yuren consider He Zheng feeling toward her is that He Zheng is not like the other men in their class. One needs to say internship is busy, they also have night shifts in the hospital. A lot of work to do while studying and observing.
