Qin Zhensheng's second son, lying near death in the Qin family's private hospital. A fortune-teller told Qin Zhensheng that Buyan's fate required a daughter for him to survive. He is described as someone who lives almost entirely alone and avoids intimacy. He is also the man Hu Wanyu spent the night with three years ago. He wore a protective jade as a child, which matches the one Ningbao now has.
