"Come on, Y/N!" Izuku calls as he runs towards the shops, the green-haired boy looking back at you as he beams.

You smile brightly as you quickly follow your friend.

"I'm so excited!" The fourteen year old beams as he stops to wait for you. When you do catch up to him, he takes your hand to make sure you don't get lost in the big crowd.

You've always been in love with Izuku Midoriya. Always been obsessed and overprotective. For as long as you can remember, you were always by his side.

The two of you run up to the big window, Allmight posters and figures showing from the shop inside. You could see the excitment in Izuku's big green eyes as he stares at the window Allmight themed objects.

"Look! Oh wow, these look amazing, Y/N!" Izuku points to everything as he still holds your hand.

"Oi, nerd!" A familiar annoying voice says as it approaches from behind.

Izuku flinches at the voice, gripping onto your hand. "Oh no..." He mutters to himself as he turns to the ashy blonde.

"What are you doing here? Shouldn't you be crying to your mommy?" Katsuki grins devilishly as his posse snickers behind him.

You give Katsuki and his posse a cold stare, annoyed of his attitude and personality. And his existence.

"I'm just looking at the new Allmight merch, Kacchan." Izuku says quietly, letting go of your hand incase Katsuki teases him for it later.

"Yeah? Well move out of the way, Deku. It my turn." He grins as he reaches a hand to shove Izuku aside.

You grab Katsuki's wrist, your eyes piercing him with your cold gaze. Your blood boiled in anger, and you would kill him on the spot if Izuku wasn't there with you. You don't even realize how tight your grip is until you hear a sharp crack.

Katsuki yelps as he pulls away, his wrist very much broken. Izuku's eyes widen, and he quickly takes your hand and runs off, leaving Katsuki and his posse to deal with it.

Once you two are far enough, Izuku grabs you by your shoulders. "Y/N! What were you thinking?!" He says, green eyes wide with shock and a bit of horror. "You can't just go around hurting people like that!"

The fear in his eyes breaks your heart. You look away from him, feeling a bit ashamed from his gaze.

"I'm sorry, Izuku." You say quietly. "I understand if you hate me..." You continue, your voice trembling ever so slightly. You felt a bit annoyed with Izuku. Couldn't he see that you did it for him?

Izuku takes you hands in his and looks at you with his soft green eyes. "Please look at me." He says softly. When you obey, he sighs. "I could never hate you, okay? But you need to promise me that you won't do anything like that again, okay?" He says in a soft but stern voice.

Not wanting to disappoint, you nod obediently.

You despised Katsuki Bakugou.

Every little thing that he did made your blood boil. Made you want to carve his face off and feed it back to him. Made you want to carve his heart out and hang it on your wall as a trophy.

The only reason you didn't do this, was because Izuku would be upset if he died. And making Izuku sad was something you did not want to achieve, so Katsuki's life was spared.

Until one day, you were walking down the hallway of the school when you heard a certain blonde's voice.

"You know, if you want a quirk so much than there might still be a way." He begins as you listen into the conversation.

"Pray that you'll be born with a quirk in your next life and take a swan dive off the building."

Something inside you snapped that day. You felt your blood boil. Your knuckles turned white from how hard you were clenching them.

Something had to be done.

.

Katsuki spat up blood as he clutched his wound, trying to crawl away with you. The difficult thing about that was you cut off his hands so he would be hard for him to use his quirk at all.

You had cornered him into an old tool shed out behind and abandoned house, and this would be where he died.

You stared down at him with a cold gaze, blood splats on your clothes. You dug the scissors deep into his calf, torturing him with every sharp object you could find.

Katsuki let out a cry of pain as he tried to get away. This couldn't be the end. He couldn't die like this. He wanted to do so many things, go so many places. He held onto his dreams of becoming a hero. That was his motivation to try and escape.

You took a machete, slicing and cutting away at his arms with a cold expression on your face. You couldn't hear Katsuki's pleas and cries, all you could hear was a soft ringing in your ears.

Even if you could hear him, it wouldn't change anything.

Finally, you stopped toying with him, and dug the machete through his heart.

Katsuki Bakugou died on June 12, midnight.

Well, at least, you knew he died. Everyone else just thought he went missing. To be fair, you did chop his body to bits, and cleaned up very well. Surprisingly, you'd never done this before, but you were incredibly good at it.

Poor Mitsuki and Masaru. They were obviously distraught, so much that you almost felt bad about killing Katsuki. Almost.

They missed him so much, how could you not help a bit? Maybe you could just give them one last goodbye to their son.

Mitsuki smiled softly as she ate. "Wow..." she mutters to herself after swallowing the meat.

"This is fantastic, Y/N. You'll have to give us the recipe." Masaru said, smiling softly at you. "What type of meat is this?" He asks, tilting his head to the side slightly as he takes another bite of the thick stew.

The explosive kind, you wanted to say. But instead, you just gave them your best smile and laughed softly.

"Of course! It makes me really glad that I could make you both smile." You reply, dodging the question.

Mitsuki smiles softly at you. "Thank you." She says, bowing her head slightly. "We really appreciate this."

You left that night feeling happy that you gave the Bakugou family one last taste of their son.

You didn't feel bad, in particular. He hurt Izuku, and no one was allowed to do that. Katsuki Bakugou got what he deserved, you thought.

And you were still a good person, after all. You even watched Izuku as he slept to make sure he didn't have any bad dreams.

One day, he will love you. Who wouldn't?
