The Grand Duke of the North

Yumi, an actress with no experience in love, is terrified when she wakes up in a dark romance as Selene Belias on her wedding night! Yet instead of confining her like in the novel, her husband, "Monster Archduke" Varas, brings her gifts and takes her on outings. She falls for him... but then discovers he thinks she's a witch and is searching for the real Selene! Can this actress convince her first love that she's really his wife? Or is she to be cast out of this role that's not rightfully hers?
