It was their first actual mission together, a week after they'd been partnered up. They had been tasked with infiltrating a local drug ring operating (conveniently) near the college Oikawa went to (along with Suga and Daichi who were in fact sharing a flat in the same residence). After narrowly escaping their notice, Hinata knocked on the door, abruptly thrusting a thin file at the sole occupant of the flat had opened the door. Half an hour later, they were off to the Agency for a detailed briefing and a disguise.
It was looking to be a small mission, only lasting a day or two to identify and tag the members of the ring and call the police to pick them up. No real big case had come up in a while, making this the perfect time to recruit and match up newer agents with high level ones without any (or rather, with less) fatalities. Hence, the pairing of Oikawa and Hinata.
The first problem they had was the disguises:
"I have to wear that?!"
"…It's a mission to infiltrate a drug ring, Oikawa kun. They aren't going to be roaming around in Abercrombie and Fitch now are they?' (though Hinata wasn't very enthused to dress like a druggie either.) At least he wasn't flailing around like his brunet companion.
The second problem occurred when, of all things, they realized that Oikawa didn't know how to drive a motorbike:
"You're nineteen! And part of the Agency! How did they miss this?!"
The third problem could have been avoided entirely, if Oikawa had kept his mouth shut. As it was, he had decided to recite tales of his wonderful 'Iwa chan' all through the ride in an 'effort to get to know each other'.
The redhead, thoroughly infuriated with his partner, purposely increased the speed of his bike, leaving the brunet screaming and himself partially deaf and unable to hear the police sirens as they were caught for speeding. The cops took one look at their (fake) piercings, ratty jeans and oversized, ripped tops and pushed them in a jail cell.
"This is a nice change of scenery"
"It's a prison cell, chibi chan"
"I was being sarcastic"
