Jinjja Ttari Dorawatda

Ever since Helga Yutrit found out that she was switched at birth with her half-sister, she has tried her best to shake off the stigma of being a fake by building up her reputation as the perfect daughter of House Yutrit. Helga's efforts all go to waste, though, when her half-sister Hillianne is discovered alive. Now that the real daughter has returned to take her rightful place, Helga is plotting her revenge on the family that never appreciated her and the half-sister who is stealing her life.
