The Gloria family has long been one of the wealthiest and most prominent empires in Boston. When top students Kira and Beowulf are offered tutoring jobs at the Gloria estate, the two young men are more than willing to oblige. Beowulf is immediately attracted to the icy beauty Eterna Gloria, eldest daughter of the Gloria family. Eterna is the only daughter who's not adopted to boot. Beowulf wastes no time in pursuing Eterna, and Kira is left in charge of Eterna's four sisters -- Celia, Naomi, Charm, and Mary. But there have already been several attempts at the Glorias' lives since Kira and Beowulf started... and the matriarch Ms. Michelle Gloria seems to be keeping a very big secret...!
