Katsuki was walking through 1-A's dorm halls, on his way to his room when he heard mumbling coming from a room nearby...his eyebrow raised as he walked closer to the door, hearing the voice. He knew who it was. He grinned as he pressed his ear to the door, wanting to know what what happening and being said inside the dorm room. Katsuki didn't give two craps about eavesdropping. In fact, he knew exactly what he was doing.
