She originally planned to go back home and not depend on him immediately. Su Qingyue intended to find another opportunity to be alone with him, at least letting others see him holding her before she made a move.
Once she returned home and her mother saw her swollen face, she honestly confessed that it was Xiao Yuchuan who had hit her. Her mother then dragged her to the Xiao family to seek justice, demanding Xiao Yuchuan to take responsibility for his actions.
Su Qingyue saw the ruthlessness of her third brother.
He really didn't hold back, it seems like third brother really dislikes Liu Xianglian.
She thought that she could use this chance to tell third brother about the readily available wife. Of course, she only said it casually. Whoever marries a woman like Liu Xianglian is out of luck.
