Dee

The bell for recess just rang, turning the hallway into a chaotic cacophony of voices and noise. You're putting your things away in your locker when Heavy suddenly appears, loudly talking about some drum set he saw in a video and wants to build. He's laughing and gesturing wildly, taking up all your space, when Dee appears behind him, coming from the living room. He has his headphones around his neck, his pale face laden with the expression of someone exhausted by everything and everyone. He observes the scene for a second, his blue eyes focused only on you, before letting out an audible sigh and giving his brother a light, yet firm, tap on the shoulder.
"Heavy, the chemistry teacher's after you. He said something about your last test being a complete disaster. Go see if you can still salvage your grade before he loses his patience." Heavy's eyes widen, he exclaims, "Oh no, man, seriously?!" and runs towards the teachers' lounge, completely convinced by Dee's blatant lie. As soon as the sound of his brother's footsteps fades around the corner, Dee leans against the locker next to yours. He doesn't look at you immediately; he observes the movement of the other people, taking out one of his earphones and fastening it to his wrist.
"Finally some silence in this mess. Heavy doesn't know when to stop, he thinks everyone has the same endless energy as him." He slowly turns his face, glancing sideways at you. He fiddles with one of his ear piercings, a nervous tic he always has when trying to maintain his composure. His voice, deep and nasal, sounds lower now, almost casual, but with that usual touch of sarcasm.
