Katsuki Bakugo is the one to shout at others with such explosive and abrasive temper. Yet underneath that temper, still showed care in his own ways. —Either be that by cooking for his entire classmates, demonstrating and giving advices (painfully harsh criticism) with his classmates’ quirk identical to his with the usage of his palms, or sparring and accepting a practice quirk utilization. Contrast to his personality, he sleeps at 8PM sharp and woke up at 5AM for a morning jog or an early training, and studies extremely hard which was the opposite of his personality. Super shocking to others when they figured out his schedule.

He just knows how to take care of himself unlike those stupid extras who lack self-preservation instincts in their life!

Another thing is that fucking nerd by the name of Izuku Midoriya. After the war ended and in their continuation of their second year, he minimizes his name calling of Deku on him and more on Izuku. After all they went through and Izuku’s PTSD of his supposed death, he’d been keeping it steady. In the same way— Katsuki was always Kacchan in his eyes. It was a fond nickname Izuku gave him when they were kids still playing in the sand with their All Might action figured in hand trying to pretend play about defeating the strongest villains.

Before Katsuki got his quirk. Katsuki still hasn’t known why Izuku forgave him so easily even after bullying him for years just because of his insecurities of his nerd being more heroic than he ever was without a quirk. But then again, this is Izuku he was talking about. His stupid smile, big ass eyes, and star littered freckles.

The blonde has never heard of Izuku calling him Katsuki in his entire existence. Just ”Kacchan!” slipping and rolling out his tongue. It sounded so cute and affectionate that it didn’t seem to suit his abrasive and egoistic personality, but that nickname only bloomed further with more affection as time goes on. And he never wanted the green haired to change his stupidly nickname. After all, they were both Deku and Kacchan.

Katsuki was in the common area with the others. Self-proclaimed Bakusquad as Mina and Denki liked to call it. It sounded extremely fucking stupid. But anyway, they were finished with their internships with the other pro-heroes and decided to have a movie night to relax. It took a while for Eijiro to convince Katsuki to join them hanging out (He convinced him anyway that he needed a way to have some fun and not sulk in his room. Who is SHITTY HAIR calling sulking?) It was already late and passed his bedtime, what a shitty timing.

“Oh, Kacchan of the Bakugo’s, nice for you to show up.” Denki smirked, throwing him the remote on to his lap. He frowned and groaned. Denki calling him Kacchan sounded so wrong and so WEIRD.

Katsuki basically fumed, gripping the remote off his lap and accidentally smacking Hanta in the face, ignoring his wince. Please, just get him out of here.

“Shut the hell up, Sparky. Not like I had a choice,” He just wanted to sleep and maybe text Izuku a goodnight. “And stop calling me that! It’s so weird and childish.” The blonde grunted, making the others giggle for his response. He completely missed the rushed footsteps.

By next morning, Katsuki entered their classroom; seeing the nerd talking with Pink Cheeks. He scoffed, pulling out his seat. “Mornin’, De- Izuku.” He greeted Deku. Before he can even sit his ass down and expecting a cheerful greeting as usual..

”Goodmorning, Katsuki!” the green-haired spoke.

Katsuki paused mid way. What the absolute fuck. He thought. He’s sure the others were surprised, too, sensing the confusion in the air. He’s not blaming them, Izuku always called him by his childhood nickname. So, why stop now? It sounded so.. out-of-place and strange. Why was HE even bothered? He didn’t care.

“What.” Katsuki snarled and shooting Izuku a sudden glare, his nerd basically stiffening with a nervous smile. His mind was turning gears about what could make Izuku not call him Kacchan.
