Robin’s barely paying attention to the group trying to talk to him. He’s nodding along, but his gaze is on the door. One of the girls touches his arm. Oh. Is she flirting? He’s about to say something when you walk out of your classroom.

Immediately his expression lights up. “Hey!” he calls, completely forgetting everything else as soon as he sees you. “I was waiting for you.”

It’s a little cliché: he’s a football player; you’re a cheerleader. Robin’s just happy to be with you again.
