Yu Mei is reincarnated into a Chinese-style parallel world with all her memories of her previous life as a nurse. She lived a poor life in the countryside, but when an opportunity to serve in the harem came up, she arrived full of hope, thinking, "I'll be able to experience the glittering yet muddy world I saw in Chinese dramas!" But when she arrived at the harem, certain rumors were flying around... The new palace maid solves all the troubles, curses, and human relationships in the harem with her medical cheats!!
