This is Bakugo x Sibling! Reader

Also, this one is kind of short and a little wonky, but I felt good enough to post it.

*.*.*.*.*.*.*

(Y/N) was gone.

She was gone and it was his fault.

Katsuki's twin sister had left, and he blamed himself.

They never really had the best relationship, but that was because of Katsuki. He always made fun of her and made her feel the worst she had ever felt. He didn't hate her. His pride and anger just always got in the way.

He never paid attention to her, but Katsuki should've realized what was bound to happen.

(Y/N) had begun to joke about how no one would notice if she was gone. Everyone in her class, 1-B, always brushed it off. She was always making self-deprecating jokes so it didn't seem like anything new.

Then, she started selling her things. She made the excuse of not wanting it, and that she needed the money. It did raise a brow since their parents were known for their amazing designs. Many thought they would have enough money to give her as much as she wanted. No one really knew what she was going to do with the money or what she was buying with it.

(Y/N) had been planning to run away, and was already taking the measures to make sure she'd be set. She had a specific date where she would do it, but something made her do it beforehand.

She argued with her brother. It was just small bickering at first, but it soon escalated.

Katsuki's anger always made him say some things he didn't really mean, but this time it hit her stronger than before.

"Why couldn't I have been an only child? I just had to be stuck with you, didn't I? A weak piece of crap that no one cares about. You can barely control your quirk. I don't understand how you got into Class-B. They should've used that spot for someone better. Even if you do become a hero, I doubt people will recognize you."

"Katsuki, do you really think I don't know that already? I know that I'm weak. I know that I'll never live up to you. I know that already. You don't have to keep repeating that to me over and over again. At least, I recognize my faults, and I'm working on them. I'm trying to get better, but you're not doing anything to fix yourself. All you do is scream, and attack people. Even if it's not literally, your words are always just a bunch of words that hurt."

"I swear if you don't shut up right now...."

"No, I'm not shutting up. I'm sick and tired of you making me feel like crap. I'm sick of you always bullying me and never letting me be happy. All you are is an arrogant bastard-"

An explosion was heard along with a loud smack.

(Y/N) stumbled back, nearly falling in the process. Tears built in her eyes as she realized what had happened. The burning sensation in her left cheek made it obvious.

She slowly touched her face before pulling away rapidly from the pain. She turned towards Katsuki, hate evident in her eyes.

"Fuck you, Katsuki! Fuck you!"

(Y/N) shoved past him, running up to her room, and locking the door behind her.

He looked at his hand, seeing the slight smoke coming off of it. His eyes widened as the guilt started to settle in and he rushed to his sister's door. With it being locked, he couldn't enter, but he could still hear sobs and shuffling coming from inside.

"(Y/N)! Let me in!"

The shuffling became even more prominent and the sobs turned to sniffles.

"Come on! Open the damn door," Katsuki called out.
