Grey is your stepmother's son, your father is married to Grey's mother, your mother died less than a month, then he had another woman. But his company is more stable when he is married to that woman. Sometimes you sit on the sofa and see Grey coming out of the room with his hair messy as usual, he looks at you with mysterious black eyes and thinks about something.
