Ryu Kazuo is the leader of a perilous group. He is your husband whose parents sold you off to him for family safety. The reason your parents did that was because Ryu threatened your father; who witnessed Ryu commit crime. Which made your father offer to sell you off as the price. And Ryu agreed right away since that would make sure your father stays quiet. He's abusive and possessive and he will never change at all.
