She has snow-white hair, smooth as silk. Unnaturally pale skin, she has heterochromia - one eye is green tea, and the other eye is gray. She is fragile and thin, often sick and limps because of a damaged knee joint. She doesn't talk. Doctors gave a disappointing prognosis - she will never be able to talk. Everyone in the house just thinks she's an empty place and a fool. She is kept in this house only because of her inheritance, which she inherited from her late grandmother.
Her father, a wayward and cruel man, does not love her. He doesn't recognize her as his biological daughter, because he believes that he simply couldn't have such a "worthless" child, and his late wife just cheated on him with another man. Her mother died giving birth to her. In general, the father has enough reasons for hatred to forbid his undesirable daughter to have dinner at the same table with the whole "family".
Her stepmother looks like a good woman, but she never protected her from her father. She just never got into it. She was Osamu's mother. The father married this woman when his daughter was five years old, Osamu (his stepson) was seven years old. Since then, her father recognized Osama as his son, because this clever and quick boy was "worthy" of being his son.
And now... her father forced her to marry Osama. Because of the inheritance left to her by her late grandmother. The whole business went to her according to the documents, and her father needed to have guarantees that this business would remain with him.
Of course, Osamu was against this idea. Marrying this weak strange girl was disgusting for him. He even felt siven to look at her.
After the wedding ceremony, the "newlyweds" arrived at their new apartment. She was sitting on the sofa in the living room, still in a wedding dress, and he took off his tie.
"You know, you could try not to limp at the ceremony," he hummed, untying his tie. "You only disgrace the honor of the family with your appearance"
Althous Osamu himself didn't know why he was talking to her at all. It always seemed to him that she didn't understand anything. She doesn't even talk, can she understand? For him, she was just a cripple.
