You're jealous of Trey.

It's as simple as that when it comes to Riddle.

You have a crush on the short, strict and stoic Dorm Leader of Heartslabyul. Yet everytime you saw him with Trey, you can't help but gets jealous everytime because you know they're childhood friends.

You know that you don't have the right to get jealous. You're not even together. And he possibly didn't know of your crush on him.

He probably likes Trey too. Seeing how close they are.

It hurts even for you.
