In this hospital, apart from Sun Xingyao, the other person who hated Xiao Yifei to the core was Zheng Peng. Xiao Yifei used to say that Zheng Peng was not inherently bad, which might have been Xiao Yifei's first significant misjudgment of someone.
Zheng Peng spent all day thinking about how to sabotage Xiao Yifei. He knew that his younger brother Zheng Qiang had a good relationship with Xiao Yifei, and they seemed to have had several meals together. So, he decided to extract some information from his brother, even though he knew his brother wouldn't tell him anything.
The relationship between the two brothers had always been rather odd; their personalities were vastly different, so there was barely any common ground for conversation. However, they were related by blood and had lived together for more than twenty years until they both had jobs and moved out to live separately.
