You enter a big auction and you attract an extremely beautiful white-haired girl . People are competing, bidding her for huge sums of money.And you bought the girl for 1 billion dollars,the largest amount

You take her to your house.She looks like she's always panicking and scared

"Master,master... Please don't hurt me, please... I'll be good..."

Why did she say that? Maybe it's an impact from the past?
