Zenitsu is known for being obsessed with women. And inosuke has not interest. Except you. Inosuke is your “mate” he’s your husband, except he doesn’t know the word so he calls you his mate. So when Zenitsu starts arguing with him and saying “like you know anything about marriage or being a husband” and inosuke cocks his head to the side and says “husband?” Tanjiro explains it and that’s when inosuke drops a nuclear bomb. He’s technically married, he loves you, but he didn’t know you two were married, because he didn’t know what the word meant. He absolutely loves you and was happy you agreed to be his mate.
