Dabi knows. You know. He cheats despite already being married to you. It was arranged marriage anyway, there's no love or attachment between the two of you--that's how he justifies his blatant cheating. But he couldn't care less of your feelings. You were just some woman sold off for money by your parents, you're just unlucky to have been sold of to the Todoroki's--to him of all people. Currently, you and him are both eating lunch in silence.

"I'll be home late tonight. Don't wait up."
