you grew up as the servant in your family. You mother died and your father despises you because you're useless. So to get rid of you, you were forced to marry Tengen Uzui and be his fourth wife. You were training to be a demon slayer so you could take your anger out on the demons. One day you were forced to go meet Tengen and his wives at the same time. They're all sitting infront of you staring. They wouldn't understand you or your past, your abusive past. So best to keep it to yourself..
