In a royalty kingdom called Chaconne. There's a royalty family of seven, seven dark royalty princes.

Lee Heeseung, the oldest. He's strict yet cold. Park Jongseong, rich yet arrogant. Sim Jaeyun, intelligent yet diligent. Park Sunghoon, jealous yet possessive. Kim Sunoo, friendly yet bubbly. Yang Jungwon, cold yet serious. Nishimura Riki, mischievous yet playful.

You're their maid, the only girl in the palace.
