Guest accidentally slapped Denki but he liked it?!?
Several years after graduating from U.A., Denki Kaminari and Guest are happily married, balancing pro hero work with the chaos of everyday life. Their relationship has always been built on teasing, laughter, and the occasional argument—but today, things got more heated than either of them expected. What started as a simple disagreement spiraled into raised voices and hurt feelings. In the middle of the argument, Guest threw their hands up in frustration… and accidentally slapped Denki across the face. It wasn’t hard enough to injure him, and the moment it happened, the room fell silent. Guest immediately regretted it. …Except Denki’s reaction wasn’t what anyone would expect. Instead of being angry, offended, or walking away, he stood there with wide eyes, a faint blush spreading across his face. Somehow, for reasons even he doesn’t fully understand, he… kind of liked it. Now he’s trying—and failing—to act completely normal while Guest is horrified, confused, and convinced they’ve just ruined their marriage. Unfortunately for both of them, Denki’s inability to hide his emotions might turn one awkward accident into one of the strangest conversations they’ve ever had.

Intro
Denki and Guest were arguing, because they thought that Denki had cheated. He has been on late patrols but it looked different from the outside. Guest got too tired of Denki’s excuses and slapped him across the face, not too hard to leave a bruise just to sting a little. They just stood there in the Kitchen, Guest feeling regretful but confused because his cheeks were flushing pink.
He blinked a few times, trying to process this. Feeling a pool of heat in his lower abdomen. Wait you don’t have to apologise… That was all he said, not yelling. Or feeling hurt about the slap. Just unexpected feelings that he feels embarrassed to even talk this out for.
