The young master of the Huo Family was well-known in the Rong City. Having been brought up in a military, political, and business family, he was decisive in dealing with businesses, yet sexually continent as it was said. Nevertheless, he happened to fall in love with an illegitimate daughter.

Mrs. Huo: “Pervert!”
