oikawa takes takeru to an aquarium for his birthday because he knows they do a mermaid show in one of the big tanks. what he doesn’t know is that he ends up more amazed than his nephew when he sees not a mermaid but a merman in the water.
he moves through the fish with insane elegance, his big, muscular body flowing like silk, propelled by a long tail he handles like it’s actually real, its turquoise colour contrasting with his dark skin. no diving googles (tooru thinks it’s for the aesthetic, but his own eyes sting just from thinking), but he is wearing a gold crown entangled in his black hair, matching the bracelet wrapped around one of his thick biceps and the wrist chains.
oikawa can’t take his damn eyes off him because it’s truly hypnotic the way he moves, the way his torso and waist ripples, the way he swings his thick arms to swim. but then tooru feels takeru gently tugging at his hair, and when he looks up, finds a toothy smile and bright sparkling eyes.
“let’s go closer, uncle tooru!”
“what?” tooru blinks, his voice way too high, while takeru kicks his little legs where he sits on his shoulders.
“let's go closer! i wanna say hi!”
“but—”
“do you want me telling everyone you gave me the best gift ever or not?"
and obviously tooru can’t say no to that, being the proud man he is, so he sighs dramatically and drags the both of them to the front row spot a mom with her baby just left.
takeru waves his tiny hand to get the merman’s attention and oikawa almost forgets to breathe when the young boy swims over, bigger, broader, and way more majestic than he looked from three rows back. he smiles at takeru, pressing one hand to the glass and waving with the other. takeru giggles, and tooru glances at his nephew, lips curling into a soft smile when he sees him so excited, trying to make a heart shape with his hands.
then the merman flips onto his back, brings his hands to his mouth and oikawa’s eyes widen as he watches him blow out a stream of bubbles cupped between his palms. the guy fans out his arms just in time to rise the bubbles in two perfect columns, shaping into a heart right there in the water.
takeru squeals, just like all the other kids and a few adults, as the merman swims back, beaming with pride and then his big green eyes meet oikawa’s. and oikawa swears his heart skips a beat or two when the merman winks and smiles at him before drifting up to the surface, out of view.
“soooo cool!!” takeru yells, practically vibrating.
“yeah” tooru whispers, cheeks flushed “super cool.”
what oikawa doesn’t know either is that he’s going to see that same merman again, this time on land, during his first class of junior year, introduced as the teaching assistant iwaizumi hajime.

Oikawa and Takeru Headcannons (Timeskip and non timeskip)
non timeskip: Takeru calls Iwaizumi "Uncle Hajime" since he's known Iwaizumi as long as he's known Oikawa.
Timeskip: Went to Shiritorizawa. People think it's because he thought it'd be funny since Oikawa hates Shiritorizawa but its actually because he did apply to go to Aoba Johsai and didn't get in but he did get into Shiritorizawa.
