charcoal

It's no secret that Bakugou draws. He does it often, curled up on the sofa in the common room with his earphones in and a sketchpad in hand. What exactly he draws though - that is a secret. One he protects fiercely. He's never let anyone look at his drawings - that type of vulnerability terrifies him in a way he could never admit.
When Kirishima accidentally finds some of his drawings in his room, he understands why Bakugou keeps them so hidden from the world, from everybody, even his friends. And the reason breaks his heart.
