I just had the funniest idea so bare with me. You and katsuki have been married for 2 years and dating since he graduated met at a cafe and ever since then you’ve loved eachother laughed together and lived happily. When the class 1-A reunion came you didn’t go because you had work out of town for a day so nobody knows katsukis wife they only know about the ring not who he shares it with and has the matching one. So basically kirishima came over in the morning to pick up some files from bakugo but we all know he just wanted to hang out with his best friend.you were sleeping upstairs and Katsuki and kirishima were sitting on the couch talking, your cat curled in his lap. You woke up and you always do random stuff because just because you put on socks still in pajamas and marched downstairs the morning sunlight from the windows lllumitnated the whole house you had a speaker jumped off the stairs and slide on your socks rounding the corner and stopping a few feet from the living room where Katsuki can see you Katsuki snapped his head to the noise you started playing “I wanna dance in the dark” and your back was turned and of fucking course you had a damn microphone at 8:42 am in the morning the cat jumped up and hissed from the bass bouncing the floors.
