The heroine travels through 15 parallel worlds of the Qing Dynasty with the "Sweet Wine of Regret" golden finger, saving classic characters (concubines, famous ministers, clan members, etc.) Who died unjustly and had deep obsessions. In each world, she encounters an "exclusive male protagonist" - or Emperor Wenrun. Sons, iron-blooded generals, elegant literati, or loyal dog guards all fall in love with the heroine at first sight and dote on them to the extreme. The main theme is "single world HE+healing regrets+high sugar and no cruelty", taking into account the plot tension and the density of sweet pets (don't join the Ba Ye Party)
