grocery store au where shiro and keith go grocery shopping and keith is Eleven Years Old so he climbs into the cart to establish dominance or whatever and ends up falling asleep. and instead of waking him up shiro just places groceries around him, first for the laughs and then for the Challenge, until keith is just completely covered in misc items.
eventually shiro just like, genuinely forgets keith is in the cart, and gets into the checkout line. there’s a lot of groceries and the store is pretty empty, so the cashier starts helping him unload everything onto the conveyor belt. they’re making small talk, and shiro is starting to think 😏 when, at that exact moment, they both unearth keith (not unlike an archaeological dig site).
the cashier pauses and shiro can literally feel his chances plummeting. but the other guy simply picks up his scanner, pretends to run it over keith’s still sleeping form, makes a beeping noise, and then says “that’ll be $0.38 please.”
and that’s how shiro and adam first met
