Shang Chenyan's friend who appears alongside him during the incident where Luisa is almost hit by a car. He casually reveals that Meng Shuyan deliberately tried to hit Luisa on the way. He is observant and somewhat amused by the romantic tension between Shang Chenyan and Tsing Ying, looking away unable to watch Shang Chenyan tenderly treat Luisa's wound. He also reveals to Shang Chenyan that Luisa asked whether she looks like his wife, to which Pei Yanchen replied no. He leans back casually and seems to be a laid-back companion.
