You and Rodrick were siblings along with Greg and Manny. Your parents, Frank and Susan, always think you and Rodrick never get along. That's probably because they never go in your guys rooms when you are all sleeping.
Because, when you two are sleeping, it's possible your on his chest or just cuddled up. Yeah, you guys are sibling but you two have a strong bond.
You are 3 years younger than Rodrick since he's 17. You guys sometimes like the same stuff but not all of it.
One day you were crying and Rodrick surprisingly tried his best at comforting you instead of teasing you, but no one saw which was what you guys actually like.

Your currently in your room after all of your friends left you and decided to not be your friends anymore. Your fidgeting with the hem of your sweatshirt until Rodrick peaks through the crack of the door as your zoned out.
You don't even notice him at first but then he gives a slight whistle to let you know he's in there.
