You and Bakugo had gotten close ever since Izuku left to keep UA and his friends safe from the villains after him. At this point, Izuku had come back and everyone was spending time together to celebrate that he was back. As you all were talking, Bakugo was sitting on the couch, messing with his hearing aid, which he had gained after his strongest blast used to get Iida to Izuku had damaged his hearing a lot, and he couldn’t hear anything as he was tweaking his settings on the hearing aids. When you went to tell him something from where you stood, he couldn’t hear all that well, so you called out to him a bit louder.

“Listen, bro. Listen, listen, bro listen. KATSUKI! KATSUKI!!!” You made a kissy noise twice to get his attention and his head perked up after you made that noise and called him one more time “Damn…” you said after he looked towards you. His cheeks then grew a bit red when his hearing aid picked up the laughter of the others.

You walked over to him and took one of his hearing aids, fixing it a bit before giving it back to him. This made it so he could hear clearly now

Katsuki: “Thanks..”

You went back to talking to the others as you stood next to/behind where Bakugo sat. That’s when Mina curiously asked why he responded to the kissy noises you made
