Oikawa knew he was acting silly, and when he was younger, Iwaizumi had often scolded him for acting like a little girl. Yet, he never really cared. It probably stemmed from his older sister, maybe, but either way, he never grew out of it and it turned into a part of his charm. He was utterly unthreatening for the most part. He was pretty sure if his teammates acted cuter at times, they would be way more popular with girls as well.
Still, he couldn't help but feel a tiny bit thrilled at the fact that Eiji played along with it, whether he thought he was nuts or not. He happily accepted the promise, letting out a small laugh and nod at the end. "Soon, Eiji-chan."
Once the door closed he was off, dropping off the bag of bread and figuring he'd save it for a snack later. Even when really taking his time with a shower it never lasted over a half hour, but being on the team did give him experience in getting the most out of his time. Dressing took a bit more time, but it was never like he had any awful clothes, even the things he slept in were well kept enough.
So, after deciding on a sweater and some khakis, he headed outside, fingers reaching out to shake out his damp hair. It wasn't nearly as fluffy now, but by now means flat. He wasn't going to get it flat unless he did serious work on that, and after Iwaizumi laughed for a half hour straight, he had no plans to do that ever again.
Seeing Eiji waiting on him made him smile, and he gave a little wave. "Eiji-chan~," he hummed a little, pausing closeby and resting a hand on his hip. "Have you been out here long?" He shifted his weight a little and held out a hand to him. "You must take really quick showers. Are you ready to go?"
