The summons for this mission had come at a very bad time. Not that it was sent at 3 am like the previous (very memorable) one, but a bad time nonetheless. Oikawa had kept in contact with very little of his old volleyball teammates and rivals (almost none in fact, given his job, but appearances had to be kept and disappearing would have been counterproductive) but one of the most notable people who had to deal with his whims, fancies, and alien conspiracy theories (other than Hinata and occasionally, Tsukishima) was his best friend, Iwaizumi Hajime, or Iwa-chan, depending on who you were and how much you wanted to piss him off.
As it happened, Iwaizumi had been convinced (read: forced) to a nearby mall with Oikawa when the summons came in the form of a tall blond.
Dressed for once in a formal black suit and with the frustrated look that Oikawa knew from experience came from doing too much paper work, he walked in with his face buried in his phone and a respectable sized file under his arm. He looked up and, not noticing Iwaizumi or not caring (paperwork did that to him), scowled at the other agent.
"Bakakawa, what the hell is with you not answering your phone? I was forced to track you over here."
"Huh? This is my off day!" He frowned, glancing at Iwa- chan, who wasn't paying attention to him in favour of squinting at Tsukishima.
"Yes well the people at the border don't really work on a Monday to Friday basis now do they?" He huffed, pulling the file and slamming it in his indignant partner's arms (he had a habit of doing that. Actually, both his teammates did).
"Come on, I left Shoyo bouncing around in our office" and with that he spun and stomped off, fully expecting Oikawa to follow. And throwing Iwaizumi an apologetic glance, follow he did, practically skipping to the taller blond and whining about work on a Sunday. ( "You should have expected it. Happens often enough.")
The next week when Oikawa came by to Iwaizumi's place, he was wearing a full sleeved shirt despite the heat (the stitches on his arm would have been suspicious). He was also carrying a small pastry with him as an apology for ditching him last time. Not that he'd needed to, Iwa had gone back home in peace and then spent some quality time wondering where he knew the blond from, and why name 'Shoyo' was so familiar.
Oikawa's good mood diminished when, without beating around the bush Iwa shot the question at him. "You work with Karasuno's Hinata Shoyo and Tsukishima Kei?" he was saved from answering when the landline rang and his friend had to go answer it, and he used that time to make a hurried phone call of his own to Tsukki to get their cover story.
The next day, Tsukishima was heard complaining to Hinata about their brunet teammate forgetting the cover he'd made them. "Well, it's not like you're all that great at lying either, despite your poker face"
"…"
"Kei kun? Is this one of those times you wanted me to lie to you to protect your delicate emotions?"
