Empress flower garden

I will survive the fierce competition and return to my original world!On what should be the happiest birthday, I get sexually harassed by the store manager, and then get hit by a truck and die. When I wake up after a flash of light... a historical drama set? No, another world??? And before I can even adjust, I have to go to the palace tomorrow. "Can I... become a court lady?" "Court lady? What do you mean a woman who will become a crown princess?" This world is a country ruled by women and men are concubines. It's not hereditary, but the 'crown ladies' who are candidates for the next emperor compete against each other and the final winner becomes the 'emperor'. The moment I hear that, I think of what the strange old lady said... "Is there a law that says women can't become emperors?" Ryu Jeong-ha suddenly gets involved in a blo*** battle for the throne. Will he be able to survive and return to his original world?!! filled with a charismatic empress and beautiful male and female concubines!
