it all started when satoru had the smart idea to smack a water balloon against suguru’s back while he was outside training the second years in the burning sun.

suguru had gone stiff from the sudden impact and the water soaking through his clothes. and before he turned around, all he could hear was the white-haired man’s giggles from a distance.

and when he did turn around, he found satoru and a bucket of water balloons.

this is what he was doing instead of teaching the first years?

little did suguru know that it was the first-year students who had filled the balloons with water.

“my students and i will beat yours, you know that, right?” suguru said, challenge evident in his tone and a crooked smile on his lips.

“well, hold on, who said i’m staying out of this? no way. so, obviously, we’ll win,” satoru declared smugly.

to which suguru replied, “no cursed energy use allowed. including infinity.”

and that’s how both of their students got dragged into a water balloon fight. not that they were complaining; it was nice to destress, and getting doused in water wasn’t the worst thing considering the hot weather.

“pffft, what kind of throw was that, inumak-- oof.” satoru was halfway through cackling before two water balloons burst square on his chest by panda and maki with no remorse. it wasn’t often that they were able to hit their teacher after all.

suguru only chuckles, eyes closed with delight and pride directed at his students. and it even earned a quiet, amused laugh from megumi who satoru’s head snapped towards with incredulity and betrayal written all over his face.

“you’re on my team. why are you laughing?” satoru almost whines, very much (not) like the 28-year-old he is.

another loud smack! echoes off satoru. his back this time, and he stumbles forward slightly.

“don’t you know that you shouldn’t turn your back towards your opponent, satoru?” suguru says, voice as sweet as honey, like he didn’t just hurl a water balloon at satoru with all his force.

it only escalates from there.

everyone was practically drenched by the time you came outside to see where everyone was - your husband’s classroom, which was supposed to be occupied by him and his students, was empty when you checked.

he’s wearing his tinted, rectangular glasses, hair down and wet, his skin catching in the sunlight, a halo seemingly appearing around his head. and the most radiant thing out there isn’t the sun. it’s his carefree smile, his laugh floating in the breeze and wiggling into your ear canals, hairs dancing in response.

a smile of your own tilts your lips up affectionately as you walk closer to them.

he’s the first to notice you, of course. and somehow his grin brightens, almost blindingly, competing with the sun.

“hey, baby! wanna join our water balloon fight?” he asks immediately, handing you a water-filled balloon. “i’m getting bullied out here.”

you giggle as you approach satoru’s side, noticing how his clothes are soaked through. you take the balloon from him, shaking your head woefully in a dramatic act. “oh, my poor husband. don’t worry, i’ll save you,” you tease.

“my knight in shining armour. ha! watch out, everyone, my wife’s gonna--” four water balloons hit satoru consecutively, cutting him off once again. “see, i told you! i’m getting bullied. they aren’t even targeting my students as much as they’re targeting me!”

a pout begins to form on his pink lips and you pat his back softly, unable to help the small laugh that tumbles out. seeing the strongest rendered helpless because of a few water balloons.

“don’t worry, we’ll get our revenge, my love.”

it’s safe to say the same thing happens in winter when it begins to snow and satoru makes the first snowball.
