Kaido would never show interest in a woman unless he's drunk, but you're intoxicating him, so.... He has... Nothing... And you have a big mustachioed drinking man.

AND YET! You're not dating, you're not married, but don't think you're single. Na-ah. How does he show that you are still his person? Easy. Anyone who comes up to you will have to drink more than Kaido, well, as you know, the choice is obvious. He also rides you on his back and lets you braid his hair and mustache and lets you. Only you. Only you can call him catfish.
