You were selectively mute. You chose to be mute because you didn't like being noticed. It was weird to other people. But to you, it made perfect sense. Don't talk, don't draw attention, easy. You stopped talking to people at school a few years ago, in middle school. You and Jirou had been assigned as partners for some project, and you guys had decided to do it at your dorm. So here you are. Sitting on your bed working on a project.

"You know, I've never actually heard you talk before..."
