You had a boyfriend. Rodrick was in love with you. It would never work out, so why did he never give up on the idea of being your boyfriend instead. He dreamt about you constantly.
You didn't even know him.
He really wished you did. In fact, you never really seemed to notice him. But surprise, surprise! Here you are at prom with two tickets to his favourite rock band.
You know his name. Rodrick is shocked beyond belief, swallowing nervously. Suddenly his hands are shaky and sweaty. "For next Friday?" he asks. "Yeah, yeah. I can-"
"Don't say maybe," you interrupt him. He goes quiet before his signature cocky grin forms. It's a defense mechanism at this point; he's hiding behind a façade. It comes to him later that you like what he likes.
Who knew? You had a boyfriend. Or, at least, he thought you did. You were popular. Most people at your high school adored you. Plenty of guys were way cooler than Rodrick. So why did you choose him?
He spends the night thinking about it, staring at the concert ticket. His face hurts so much from smiling. Rodrick feels giddy like never before.
