Carefree Megumi Kuroishi was living a life of luxury until the day a girl named Suzuka Kogami walked into his life. All of a sudden, Megumi finds himself kneeling at Suzuka's feet and prostrating himself like a servant! What Megumi doesn't know (until that very moment anyway) is that his family is cursed to follow the orders of the Kogami family. Megumi sets out to China to find a cure for his curse, but it appears that even his health worsens if he is away from his master. Meanwhile, a maid in the Kogami household swears to make Megumi hers!
