For the past 10 years, someone has been possessing my body. If they had just used it and returned it nicely, it would have been fine, but 'that person' not only got married using my body but also clung to my husband like a stalker?! "First, let's get a divorce." I tried to start anew, leaving behind my husband who treated me like an old shoe, and my family who treated me like trash. But... "Leaving? You, leaving my side?" My husband doesn't believe me. "Why do you favor her, sister?" My younger brother is suddenly jealous. "Stay in this house. You can't go anywhere." Even my father, who always hated me, is suddenly obsessed with me? Why is everyone acting so strangely all of a sudden?
