There was no way Atsushi would make it back to the others before the fireworks started; he was still on the footpath that wound its way around the main avenue of stalls at the festival when he heard the high-pitched hiss that heralded the first fiery explosion of color(more) above the water.
He stopped hurrying though he kept moving, eyes glued to the sky and not to where he was headed and as such he predictably almost walked into someone else stopped along the path to watch the fireworks.
"Oi," his unintended victim said harshly. "Watch where you're going-" Another round of fireworks illuminated them both, and Atsushi stared wide-eyed at a now equally surprised Akutagawa. He was clad in a dark-colored yukata, and had a kitsune mask on the side of his head, presumably to help disguise his appearance because there was no way that Akutagawa would wear a mask at a summer festival just /because/-
Their shared heartbeat of startled surprise ended with another burst of fireworks but Akutagawa's glower had strangely softened at the edges. "Akutagawa," Atsushi said, warily, his attention drawn by spirals of color in the air and when he glanced back at Akutagawa, nerves on edge, he found that Akutagawa was watching him and not the fireworks.
"Neutral ground," Akutagawa said, holding up one hand before raising his eyes to the sky to watch the remainder of the display. After a guarded moment, Atsushi followed suit and was immediately captivated - and did not notice that Akutagawa's attention once again fell to him and not the fireworks above their heads.
When the fireworks display ended, Atsushi sighed and looked to Akutagawa - only to find himself alone on the footpath and Akutagawa nowhere to be seen. Although he was strangely disappointed, Atsushi didn't linger.
