Work Text:
It's been months since the end of the war, since izuku destroyed shigaraki and himself along with him.
Even though it had beed ages since he died no one had cleared out his dorm or room. No one had even been in there since it happened, not even inko.
Everyone was grieving the loss after the war. Everyone has had horrific things happen to them in that war so Katsuki shouldn't be so sad. He mustn't.
Even if he'd known izuku the longest or that he'd seen izuku in a way no one else did or the fact that the image if izuku's lifeless (and armless) body in a pool of its own blood had burned into Katsuki brain.
𓏵
Inko had asked Katsuki to help her clear out izuku's room. He obviously agreed to. Katsuki couldn't just leave the old woman to do it all my herself.
So on the weekend he went over to izu- inkos house. When Katsuki walked in the house
As Katsuki walked into the room of his late friend, the light smell of mint lingered in the room. The room was filled from floor to ceiling in all might merch, that damn nerd had always worshiped him, it also had a few notebooks scattered on a desk. His bed was unmade as always.
The room looked like izuku had just stepped out of it and would be back any minute.
He stood there taking in the sight of the room.
"Katsuki? Are you alright?" Inkos soft voice broke him out of his thoughts.
"yeah, auntie, I'm fine." He replied quickly. He wasn't fine, he felt like he was about to erase him, his friend, his rival, his everything.
"if you say so. Katsuki you really didn't have to do this i know how hard it it to lose a friend." Katsuki wouldnt described him and izuku as friends. They had always been something more something that he couldn't name.
𓏵
As Katsuki started putting all of izuku's things in a box, he noticed a paper sticking from under the bed.
He bent down to retrieve the paper.
It was a letter? Addressed to Katsuki? It looked old.
Wrote on it was:
'I'll probably never give this to you but I have to tell you. I've liked you for the longest time. Ever since we were kids, I've had a big crush on you. I think your amazing, Kacchan. I never hated you, not for a second, even in middle school when you hadn't necessarily been the nicest person to me. I had admiration for you. Your bravery. Your strength. Your weaknesses. We have been through everything together. All my memories contain you. I'm just so scared that you don't like me back because I've seen you with kirishima. You two were close since first year. I just hope that one day you'll be able to look at me the way you look at him.
-Izuku'
Katsuki was stunned. He'd always thought the nerd was a bit red whenever he talked to him, and always started to mutter near him and he'd noticed that izuku always complement him and he always saved the las-
The signs had always been there.
How had Katsuki been so blind to it.
Katsuki shoved the letter into his pocket and countined to pack the stuff trying to act like nothing happened because nothing had happened it was just a letter.
𓏵
After a few hours of packing Katsuki had finally finished. Inko had offered for him to stay for lunch but Katsuki declined the offer. He needed to be by himself.
The moment he got back to his house, he rushed to his room and slammed it shut. He slid down the door.
Katsuki reached for the letter still in his pocket rereading it over and over again.
His breaths got quicker the more he sat there. His eyes filled with tears. The same thing he use to make fun of izuku for.
God, he really was pathetic. Crying over some stupid letter.
He felt the tears roll down his face, his vision blurred. Katsuki desperately tried to wipe away the reminders of how weak he was.
It was pointless to even try.
Katsuki broke down weeping, hold that stupid, stupid letter close to his heart.
After a few minutes of this pathetic act, his breathing slowly went back to normal. Katsuki picked himself off the floor. He'd taken the letter and shoved it in a place no one would find it.
𓏵
It's been 4 years since izuku died.
Katsuki had finished school, kirishima was his boyfriend and he was moving out of his parents house to move into a apartment with his boyfriend.
Today he was finishing packing up all the stuff in his room to move. He'd already done a lot yesterday with the help of kiri.
He was going to pack all the stuff under his bed. Which was quite a lot of things.
𓏵
When he was half was through, something caught his eye, at the very back there was a crinkled pice if lined paper.
Katsuki read what was on it.
He'd forgotten about the letter completely. It felt wrong to still have it. He had a boyfriend now, so he should throw the letter away.
He couldn't bring himself to. It felt like the only thing he had left of izuku. And throwing it away would be like throwing him away forever.
So Katsuki kept it.
𓏵
It's been almost 9 years since the death of izuku.
Katsuki was now a pro hero and engaged with kirishima.
He'd kept the letter. He kept it in a little box. That box also contained a picture of izuku.
Whenever Katsuki felt upset he'd get the box out and look at the confession of love written years ago and stared at the photo of the man that had once been his everything.
No matter how hard he tried to deny the fact he still loved the green haired boy he couldn't. Katsuki loved kirishima, he really did but nothing could compare to izuku.
