Okay, so Trigger Warning. This one shot contains graphic descriptions of sensitive subjects. If you are easily triggered, I suggest you skip out on this one. Alright, onto the story. One more thing, though:
                      Stay Safe
Him-17
You-13

Midoriya
After the last day of school before break, you'd been followed home by Aika, the same girl who had been bullying you since 1st grade.
"Hey, you little whore. What's the deal with stealing Daichi from me?"
"Oh my fucking GOD, Aika! Give it a fucking rest already! He chose me over you, that's just the way things went, now shut the fuck up and go home."
You really weren't in a good headspace, since she'd been fucking with you all week. It was hurting you mentally, emotionally,  but most of all, physically. You had been cutting yourself with the shards from your wings all month, due to pressure from school and bullying.
"You know, Daichi doesn't even care about you. I saw him kissing the new girl, the other day. How funny right? What was it you said..oh! 'He chose me over you', hm? Well as you can see, I guess neither of us matter to him, now."
By now you had tears in your eyes. You were in too terrible of a mental state to consider that she could be lying. You turned away and ran home, sobbing. You bursted through the front door.
"Hey, (Y/N)- oh no are you alright?!"
You said nothing as you brushed right past Izuku. You ran to your room and softly closed the door. You layed yourself on your bed and cried. You sat back up, still sobbing, deployed your wings and picked a shard off after crystallizing them. You took off your school uniform jacket and began carving the word 'worthless' onto your arm. When you finished the last 's', you heard footsteps coming up the stairs. However, it didn't completely register until Izuku had come upstairs to ask you what was wrong. He softly cracked the door.
"(Y/N), are you al- OH MY GOD NO!"
He slammed the door open and ran to you. He snatched the crystal shard away. You desperately reached for it back.
"GIVE IT BACK, PLEASE ZUKU!"
"NO, (Y/N)!"
He threw the shard out the door. He then brought you close and held you like you were going to disappear at any second. You then felt him begin to shake and your shoulder become wet. He was crying.
"H-How long have you been doing this?"
He choked out through sobs.
"...All month.."
He began to cry harder.
"No..no no no no! This is all wrong! This wasn't supposed to happen to you! Please don't do this, I'm begging you!"
"Why are you so upset about it? It's not like I matter or anything."
"W-What?"
He stopped crying for a second. You then showed him your arm (not to show it off). Worthless carved deeply into it.
"(Y/N), no..."
He said softly, trembling. He closed his eyes, sobbing, saying things like 'no' and 'why' over and over again. He was now on his knees in front of you while you still sat on your bed, grasping your smaller hand in his large ones, holding your hand to his head. You petted his head with your other hand.
"Zuku, calm down it's okay."
He looked up at you.
"Calm down? It's okay?! How am I supposed to calm down when my baby sister is suffering to the point where she's carving her arm, like she's just some worthless piece of meat, even though she isn't?! I LOVE you, (Y/N)! You're the only sister I've got, and I care about you so, so much!"
"Well then you're wasting your time. You should just focus on being a hero! I know how important that is to you! I know you'll make a great one-"
"DON'T CHANGE THE SUBJECT! Don't you dare act like this is nothing. Don't act like you don't matter."
You couldn't really talk about your feelings too long without beginning to joke about it.
"But, like, I don't matter though, ahaha."
"...Are you serious right now? Are you really gonna start making jokes?"
"Well I mean, hey. I'm the only joke here, so-"
"STOP IT! Stop it right now! You're being ridiculous. You are not a joke! God, I understand that you must be going through so much right now. I can't say I know how you feel, because everyone is different. I also know that everybody has their own way to cope. But as long as I'm around, this..this is never going to be an option. I know that it's hard for you to talk about how you feel, and that's okay! But when you're ready, come to me, okay?"
He pulled your smaller self on the floor and held you like he used to do when you were children.
"Okay."
You said, beginning to cry.
"Shhh, it's okay. Let it out. Let it out."
He rubbed comforting circles in your back until you fell asleep. He used the first aid kit to tend to your wounds, tearing up a bit while doing so, wrapped your arm, and tucked you into bed.

Alright, since I don't want to make this too long, these will be split up into one shots. There will be self harm one shots and suicide one shots. You can recommend characters you'd like to see in a one shot right here       >
