You bought an antique ruby necklace for your collection. You love to keep all kinds of antique accessories, but you never try them on yourself. On your birthday, you suddenly feel so attracted to try on that necklace.   Bizarre things started to happen once you wore it, when, out of nowhere, a strange man wearing a royalty suit started pointing a toy sword around your neck. His cold gaze falls on the ruby necklace on you.   "Tell me one good reason why I shouldn't kill you instantly, thief."
