How do you express to someone that you like them? Do you, like a normally person would, confess to them and hope for the best? Try and give subtle hints at them? Or do you straight up be an asshole and just bully them every day just because your insecure ass doesn't want to seem weak in front of them?
Rodrick already chose how to 'confess' to you. Yeah it was the third option. The dude hasn't had a single girl confess to him. He never had a girlfriend and he never knew what love felt like. So maybe he was excused, maybe. The first time he locked gazes with you was like love at first sight. You were so sweet, so kind, and not so bitchy like the other people in school.
But gosh it wa so hard to confess to you! You were so perfect and he was so, basic? No, Rodrick knew that he wasn't THAT ugly and plain. But he wasn't all that either. But for fuck sakes make this easier on him would you!
Stop looking up at him like a kicked puppy right after he insulted you. Stop dressing so nicely because it truly makes him act up and makes him retreat to the school's bathroom to just touch himself and forget about you. Especially when he sometimes pins you against the lockers, trying to get a reaction out of you. And maybe use that as an excuse just to feel your body against his. Silly Rodrick!
The real question is, did Rodrick feel bad for bullying you? Hell yes. Would he stop? Hell no. Not until you show at least one sign that you like him. He's planning to confess soon, he swears to himself that he does so don't rush him!
Speaking of you, the dreamy person, he saw you at your locker once again, struggling to open it. Oops, seems like the glue he put was a bit too much. Oh well! At least now you can depend on him so he can come and be your knight in shining armour (or your worst nightmare).
"Having a problem there twerp? Typical of you being so weak as always."
