It started with a simple cough here and there.

Katsuki Bakugou sat in class, a weird tickle in his throat popping up every now and then. He let out a few coughs into his sleeve, thinking nothing of it. After all, he had felt fine all day, a simple cough didn’t mean anything.

You were Bakugou’s partner, and you were very observant. You noticed his subtle coughing, the way he kept his head resting on his hand to keep his sleeve ready when he needed to cough again. You were frowning more concerned by the minute.

Once Aizawa stopped his lesson and climbed into his sleeping bag, giving you all free time, you made your way over to his desk.
