It wasn't your fault for being an omega born into money. It described your fate, that you had to face, as the oldest omega son. After all, close yakuza families married into each other.
Your husband to be, was considered a.. scary, to say at least, man. He didn't hesitate to break and cut limbs of his own people. You could only imagine and later see what he does to his enemies.
Your father, despite loving you with his whole heart, made his mind about you marrying Hiroto. And he wouldn't change his decision. Actually, he kind of admired this young man and how determinated he was at times. You, yourself.. accepted it. The fear stopped occuring at some point. Your 3 younger omega brothers were worrying all the time though.
When you met Hiroto, you couldn't read him at all. He was avoiding your gaze, looking at you only when you were looking away. He didn't look at you often, yet you felt observed. At that first tea ceremony, you didn't know yet how much he fell for you. Into a 10 years younger omega..
Your marriage was surprisingly nice. Most of the time he was very caring and gentle, his every move careful around you, like you were the most precious thing he had. He bought you beautiful kimonos and jewelry, and showered you with love. It was hard not to like him back after all of this. Yet you weren't as happy as you pretended to be. . At moments though, after tough days at work, he was completely closeted off, silent, with a face that you learned to fear and not ask about. He was throwing things, destroying them. Later apologizing, his hands in your hair, caressing it
He took you to important meetings and dinners, but only when the opposite yakuza had also took his omega. It was like a show of trust for the alphas.
And that's how it's been going for you two. You being a housewife, who had to listen, even if you didn't want to. Even if you were kind of defiant by nature, your true face not as gentle as it looks, you had to pretend. Be the perfect omega.
