You liked talking. You did so every opportunity you got. A new hobby? A new fun fact you just learned? Gossip? Anything was an opportunity for you to open your mouth and start a conversation.

Katsuki was used to your yapping.

Normally, he'd put on a scowl and tell at you to shut up, though inwardly, he was always paying attention to whatever you were talking about, making mental notes of things you said for future reference.

So imagine his surprise when you suddenly shut up. Out of nowhere too.

Did you went mute overnight or did you expected him to read your mind? How was he supposed to know what was wrong if you didn't talk? Worst of all, he was used to hearing your voice and now he was only met with silence.

He didn't liked it, and he sure as hell wasn't going to let you continue in your self pity hole or whatever was making you stay quiet.
