An invite to a game of beach volleyball.

"See that net we got set up over there?" the guys said, pointing. Indeed, there was a net where he had pointed. The kind used for volleyball.

"Yeah?" Izuku asked, looking at it, putting the pieces together.

"We're setting up for a beach volleyball game, but we got an odd number of players, and you guys happened to be passing by," the girl replied, looking obviously at Izuku's muscles, an approving glint in her eyes, before meeting Ochaco and Momo's gazes briefly. Their expressions were friendly enough, but there was enough of a subtle undertone of, "You can eat the eye candy, but he's ours, so toe the line," in them for her to get the hint and refrain from openly flirting. Not that either were opposed to further sharing Izuku, but a bit of an in needed to be established first.

"So, you want one of us to join?" Momo asked, her eyes gleaming with excitement.

"Or all three of you. As long as the numbers even out, it works just fine," the guy nodded.

Ochaco and Momo both seemed game, and Izuku considered it. Was this what being popular felt like, to have people actually give him the time of day and offer to let him join in on things? He had to admit, he could get why people in that position could get a little full of themselves after enough exposure to that feeling. He didn't excuse it, but he was starting to get it. After a moment of consideration, he came to a decision.
