Sora had raised a hand in turn to wave back excitedly before Lea actually spoke up, and in no time at all he was making his way over.

"Yeah, sure I do!" He... wasn't actually sure if he had somewhere to be soon (he'd hardly taken the time to memorize his schedule), but he wasn't about to say no regardless. He all but ran over, only slowing to a walk once he was significantly closer. Confused as he was, the smile he gave the figure standing next to Lea was as friendly as ever. He trusted him enough to explain himself, at least, and he figured that any friend of his was a friend of Sora's (honestly, Sora wouldn't have said no to being introduced to literally everyone on campus-- he just liked meeting people).

"Uh, hey, nice to meet you!" He glanced sideways at Lea. "So... I guess this is one of your friends?"
