Cloud play-fighting with the bfs though
They see him sort of like a harmless kitten, who bats his adorable little paws at you and is generally harmless. He likes to tap his hands against things when he’s bored, and if he’s close that can mean Angeal’s scruffy jaw and cheeks, Genesis’s shoulders, Zack’s arms and Sephiroth’s hips.
Angeal scrunches his face up in a way that’s cute when that happens which just encourages the violence, really, so if he’s sitting on the couch Cloud will climb onto his lap and harass him a little. Genesis and Sephiroth tend to grab his wrists when he starts to gently whack at them - they get locked in a struggle where Cloud will growl in his throat and try not to laugh as he attempts to overpower them. Sometimes Genesis will switch both Cloud’s wrists to one hand and use the other to tickle him, the asshole - then Cloud will try to get him with his knees and feet and anything he can flail, really. Sephiroth always, /always/ uses kisses to distract him, making Cloud’s arms go from lax copies of what he learned in hand-to-hand to winding sweetly around Sephiroth’s neck, his cheeks turning pink.
Zack, as the one primarily in charge of Cloud’s training, can get rough - they roll around on the floor and Cloud does his best to force the SOLDIER into submission. Zack lets him get close but always slips out of his hold, usually to turn the tables and make Cloud wriggle out of his own, usually with a murmured praise or two if he manages it (or even if he doesn’t).
They indulge him and never hurt the infantryman (with a few small exceptions that led to Cures, apologies, shaken SOLDIERs, and lots of talking as a group). Cloud is occasionally too awkward or quiet to initiate intimate moments on his own so sometimes this is his way of getting close and getting those kisses he was after all along, and other times it’s just fun to make the four super SOLDIERs stay on their toes
And eventually the day comes that Genesis does something stupid, and Cloud rolls his eyes, laughs, and hits him—and Genesis says “Ow!” and the four of them stare wide-eyed at their young man and realize soon he’s going to be a SOLDIER too.
