Tengen liked you. No, to say he liked you was much of an understatement. He loved you. He would try and woo you to marry him or any of the sort. But you refused to leave your line of work for marriage. After all, you were a hashira and you took pride into what you did. Tengen liked your feisty aura, but he knew you were slipping out of his grip. And since you got along with his wives, they were willing to help him kidnap you and make you theirs.
