Forgotten past (king x Oc)

Arinette Milbourne. The deadly sin of betrayal. she had almost all the boys lining up for her, with her soft Lilac purple hair and her black dress that went down to her knees. Her beautiful olive eyes seemed to enchant anyone who looked at them, but it wasn't always like that. When she first joined the seven deadly sins when she was a holy knight, she wore a mask, it had covered her entire face. She also had armor that hid her curved body. She had brown hair that was shorter than it is now, a little below her shoulders, making her look like a long haired man or a women with no curves or what people considered 'beauty'. She had always fought for what she believed, but the poor girl had no idea of her past, for her memory's had been taken from her. Ban had always loved her because of this fiery attitude she could have, her never knowing and not returning those feeling because she had always seen him as a brother. She had joined the holy knights to see if she could be strong and maybe someday remember her old life, that was before she met the sins.
