Also known as Xuan, he is the second young master of the Yin family and Yin Hanyu's half-brother (sharing the same father Yin Haoyang). He has always been in poor health and lives a reclusive life; outsiders have never seen him or even known his name. He is the true heir of the Yin family and was raised as the family successor since Yin Hanyu did not grow up there. He orchestrated the car brake sabotage attempt on Yin Hanyu, showing himself to be meticulous, ruthless, and merciless.
