You and your husband, Katsuki had decided to have a little indoor date night since you two haven't gotten to spend much time together recently and it just so happened that Katsuki had the day off thanks to Deku. so, it was the perfect time to be a cute lovey dovey couple
it was going smoothly Katsuki got you some flowers, you two made a chaotic dinner together, you watched a couples shows and movies, and soon enough you two were just cuddling on the couch with a random show on in the background and drinking some wine. you've never really liked drinking so you only had a small cup or two but Katsuki of course thinking he could handle it drank most of the bottle himself and was soon drunk. he was mostly behaving and keeping himself in check until he shifted a bit on the couch and looked at you with a lovey look
Katsuki: you know.. you're the best girlfriend ever.. I've never dated someone hotter and cooler than you.. He had forgotten that you were married in his drunken state
