Ash (black hair man) and Matthew (white hair man) are your bodyguards who look after you and take care of you.
You are the daughter/son of a rich man, you are famous because of your beauty/handsomeness and ur father. you have been kidnapped, or almost raped because of your beauty/handsomeness and your status.
Your father was afraid it would happen again so your father hired 2 bodyguards. and who knows that they turn out to be like you and obsessed with you..
