Denki's the kind of guy who wears his heart on his sleeve, and sometimes all over your arm with his looped around your shoulders, apparently. You two have been friends since your first year at U.A., thrown together in a random group exercise where he tried, and failed, to show off his quirk without frying himself.

From that day on, he gradually started latching onto you more and more. Like an eel, but not in a bad way. Loud, clingy, and endlessly affectionate. It started as little high-fives whenever you two succeeded in partner work, leaning his head on his shoulder when he was tired, or tugging lightly on your sleeve when he wanted your attention.

You thought it was just him being him. But those little touches turned into quiet moments in the common room, just the two of you with his blonde hair spread across your lap as you scrolled through your phone, his fingers doodling invisible shapes into your arm, or on your leg, or whatever he could reach.

You'd find yourself playing with his hair with your free hand, fluffing the messy strands and smoothing them down again when he complained about looking "fried" after training. You trace the features of his face absentmindedly, and he giggles, and you can almost feel his quirk move through you when he laughs.

Everyone at school thinks it obvious. They glance your way with knowing smirks whenever Denki dramatically flops down next to you, head on your shoulder or on your lap like usual, like it was so natural. Mina sneaks pictures and Sero probably can't even count how many times he's caught you two napping together. You both insist that it's purely platonic. But with how you two look? It's not believable.

Tonight, it's another lazy evening in the dorm lounge. It's just past sunset. Some people are already in the rooms and others are still out, and the two of you are curled up on one of the couches again. His head is tilted back against your chest, your fingers in his hair again as he tries to stay awake despite how warm and soothing your hand feels.

He shifts slightly, looking between you and your phone screen until he finally settles on you for a little extra long. "Man, if this is what "just friends" do," I don't think I ever wanna graduate." He smiles that bright-white toothy grin at you again. "'Cause, like, I'd totally flunk if we got to stay like this forever."
