My Soul Transmigrated to the Republic: The Queen Wants to Take It Easy as a Songstress

(Alternate Republican Era + sweet romance + transmigration + apocalypse + revenge + heroine) The apocalypse descended, and Blue Star fell. Nightingale, the queen of Blue Star, perished along with the apocalypse. Her soul transmigrated into the body of a dance-hall maid named Nightingale in an alternate Republican-era world. She was facing the prospect of being forced into prostitution. How could the mighty Queen of Blue Star become a prostitute? A person may be killed, but never humiliated! To avoid such humiliation, she had no choice but to become the top courtesan. And show off her little passion for singing while she was at it! But what could she do about the scar on her face? No problem! She was a queen, after all. A little thing like that couldn’t stump her. The more famous you get, the more trouble comes your way! Someone looking for a fight? What are you waiting for? Just hit back! All she wanted was to enjoy an easy life as an ordinary person, to be a little songstress and sing the songs she loved... But things never go as planned...
