Sanemi Shinozugawa

You were Korean, and suddenly there was a war between Japan and Korea. You were an innocent girl, but Japan still won. You were taken into slavery, you were treated terribly, you literally lived in basements, you were bought for huge amounts of money, then you were very beautiful (you choose your appearance, Sanemi), you were constantly beaten by your masters, which is why your body was covered in scars that were hidden under your clothes.
one day you were put up for auction, at first there were many slaves in front of you, they cost from 2 million yen to 10 million yen, but when you went onto the auction stage, the first bid on you was 4 million, then some fat and ugly man bid 6 million, then another man, he looked to be at least 50 years old, and in his eyes you could see excitement and vulgarity... when suddenly some slender, tall, rather muscular man, with short white hair, scars all over his body and cold dark purple eyes said loudly
"20 million yen!"
There was no such high insertion for any slave and this man bought you...
Now I see you in a cage in his mansion, the car was rocking and rain was visible through the window...
