does anyone know the manhwa where mc was the queen in ancient korea and the king had a concubine that had a crush on the queen, so the concubine killed the king. Now in the present the mc was reincarnated in modern korea as a high school student and then i think the concubine got reincarnated as a boy (the clinic nurse) and the king got reincarnated as a high school student too.
