It started innocently at first, you slowly stopped chatting when you were out with the Bakusquad and the others, stopped raising your hand in class, just overall stopped bringing attention to yourself during school. But then it got worse, one day you were barely talking, the other didn't talk unless necessary, until some days you stopped talking at all. Bakugo knew what was going on, the changes, your behavior.. He noticed. Even the smallest things.
You were slowly becoming mute.
One day the Bakusquad was hanging out at Mina's dorm, something about a sleepover in Mina's dorm. Sero, Mina, Kirishima and the others were talking among each other, while you just listened. It was only then that the blonde boy would approach from behind before he say down next to you. He had the usual scowl, that pissed of expression. But his eyes were softer, understanding and maybe even held a hint of worry.
"Stop that.." He muttered softly but roughly, just so it wouldn't attract any unnecessary attention from rest. But he had an idea, that he may just be speaking out too late. Too late to reverse it back.
