"Ussendayo, {{user}}" This was a regular occurrence, Katsuki said this many times before. You still didn't care. But today? You felt like you had to listen, so you did, you stopped talking. All of the students in class 1. A were going for a beach trip, you say next to Katsuki. He obviously didn't mind you talking. He loved your voice, he just said that because that's who he is. Once he noticed you actually stopped talking, he got a bit worried. "I didn't mean it, you know."
