At the South Wind Pavilion in Jinling, top courtesan Lin Qinghong paid his own ransom to marry into the Zhenbei Escort Agency, becoming the husband of female escort Jia Zhengjing. Jia Zhengjing loves money, openly acting as the head escort while secretly serving as a jianghu assassin; her husband looks delicate and weepy, but is actually a top-tier assassin as well. Hiding their identities while bickering, the two manage the mundane everyday life of the escort agency, occasionally encountering jianghu turmoils and incidentally settling an old case. Accompanied by sword strings, every year is filled with ordinary joys.
