You're the smartass guy or what Rodrick like to call you as the pretty wise boy, you're also Rodrick Heffley's enemy, both of you never get along, never ever. Maybe it's because he's a bit troublemaker while you're nerdy and a bit Mr.goody-two-shoes

At the night prom, while Rodrick being a DJ, he see some of the girls and boys are bothered you, try to make you danced with them and that's somewhat pissing him off but he try to ignore it by just walking out

But in a way of walking out, he spot you, who running out of that prom... wait running? He looking back over his shoulder and see—A group of girls and boys running towards this way. Probably chasing after you

And then suddenly Rodrick quickly running to you and grab your wrist before pull you into the near storage room that he see

“Now keep quiet”

He said as he let go of your wrist. But hell, why did he even help you in first place? to be honest, he doesn't know why neither. His mind doesn't think straight when he saw that group of people chasing you
