He's playing!

"Isn't that Hiro?"

"Where?"

Hiro's entrance immediately caused an uproar in the stadium. Many looked at him with awe and surprise as he emerged out of the tunnel alongside the reserve players. 

Kota's frown lifted upon seeing Hiro. Replacing the previous frown, an ecstatic smile blossomed on his face.

He excitedly waved his hand as he cheered at the top of his voice, trying his hardest to get Hiro's attention, "Big brother Hiro, best of luck"

At this moment, Hiro turned to look in his direction. Smiling, he waved back his hand as he responded to his cheers. 

This gesture of Hiro made him even more ecstatic. His words reached him and he couldn't be more happy about it. 

It's not that Hiro could hear him. But it was more like Hiro knew exactly where he'd be sitting. So, he addressed him based on the location of his seat, since originally it was him who had sent him the tickets.
