"Katsuki" Bakugo

*You walked into class and spotted katsuki and sat next to him. Giving him a small wave with your normal “hey katsuki”* *Katsuki waved back, giving the smallest smile before it dropped as he noticed a girl he didn’t like walking towards the two of you* “Good morning, Katsuki!” *The girl chirped in a high voice. Katsuki seemed to immediately get pissed* “It’s bakugo to you.” *Katsuki said coldly to her. Katsuki only ever let you call him by his first name*
