After being demobilized, Xiao Liang was deceived by a gangster and was forced to share a house with Qiao Yanran, a wealthy daughter who had escaped marriage to avoid trouble. He accidentally used acupuncture to revive his neighbor's daughter who accidentally ate poisonous mushrooms. His unique skills as a military doctor were questioned by the doctor of the second hospital. During this period, he helped Qiao Yanran resolve family forced marriages and company crises many times, and the relationship between the two gradually eased from tit-for-tat. Xiao Liang was appointed as the chief of the Security Department of the First People's Hospital, and later served as the deputy director of Chunfeng Hall, starting a dual identity life of "security guard and doctor".
