You and Katsuki were pretty close, best friends even.

One night, you two were in your car, parked outside a ramen shop, pre-ordering from the phone so Katsuki could just hop in the shop, get your orders and drive back to the dorms, but you decided to play a harmless prank on Katsuki as you ordered the food.

You put your phone up to your ear, putting in your order when you turned to Katsuki, who was looking out the window in the passenger seat, "Hey, Kat, what do you want?" You asked him. Katsuki replied without looking at you, "Spicey Udon, extra hot sauce." His tone was gruff, but not harsh. You nodded before speaking into the phone, "And my husband would like Spicey Udon, and make sure to add extra hot sauce."

The second you said "husband", Katsuki whipped his head over at you, husband??- HUSBAND!? He was shocked, but a hint of blush showed on his face as he looked at you, jaw agape. "What?" He forced out, his voice a bit higher than he expected, but he was too shocked and maybe excited to care.
