Izuku, bloody and bruised, looks small in Katsuki's bathroom.
The silence lingers between them like death on a battlefield, begging for relief that won't come.
But the answers are close, so Katsuki pulls out his first aid kit and speaks. "Strip."

Without speaking, Izuku shrugs off his shirt, revealing the gashed shoulder and bruised set of ribs. Losing his pants exposes more wounds on firm thighs and a busted up knee that explains the limp.
Once he's in boxer-briefs, Katsuki points to his sink. "Hop up there, Nerd."

"You don't have to-"
"I ain't asking." Their eyes meet, and his glare scares Deku into compliance. Once he's sitting on the porcelain, Katsuki shoves between his legs, ripping open his supplies.
"Um, Kacchan." Izuku's fingers tap with his nerves on the sink. "How do we..."

They have time to talk. Katsuki asks the three extras to babysit Eri after the battle. He won't admit it, but he wouldn't feel safe leaving her with anyone else.
Katsuki focuses on cleaning Deku's leg wounds. "I'm gonna ask questions. You answer them, or I blow your face off."

"That's fair." The little slump of Izuku's shoulders proves he's tired.
Tired from fighting. Hiding. From being away from those he sacrificed to keep safe.
Katsuki isn't sure which one breaks the strong man under his care, but its been years of Deku 'managing' on his own.

Katsuki slowly pours cool water over one wound before he starts tweezing out the debris. "First off, why is All For One obsessed with you?"
"It's not me, exactly," Izuku admits, thigh twitching either from mental or physical discomfort. "But the power All Might shared with me."

"The greatest hero, playing house husband for your mom." He smirks when catching the nerd's blush. The memory of the woman's tears sobers him. "She cried when she saw me."
"Ah, that's... she might have imprints of memories from our childhood. It feels like a strong déjà vu."

"So we've been friends since diapers?"
Izuku's silence only lasts until Katsuki dabs the medical wipe down the freckled skin. "Yes, even if you didn't always like admitting it."
"We had a falling out?" His brain pulses with something, almost like it doesn't want to remember.

Deku's caution in his words proves he doesn't want to be honest. "Remember how I said I was quirkless before All Might gave me his quirk? You had some... feelings about it."
"Why would I care about that?" Something about the question makes Izuku's eyes shine with adoration.

"It doesn't matter." Deku smiles until the string of the ointment makes him groan. Katsuki finishes the process by taping a bandage onto the wound, moving to work on the next.
"So All For One wants your quirk. Why?"
"Because it was made to defeat his. And we did, once."

The new information makes Katsuki pause, looking at him in surprise. "Hah?!"
Izuku nods, tone bittersweet. "We thought he was gone for good. Our team wiped out the original league, too. And for years, everything was peaceful. We graduated, became pros, we...were exploring us."

"And lemme guess. The ugly thumb didn't die, and made a new boy band to annoy us." He knows this, since he's faced them a time (or six).
Izuku opens his mouth, but no noise comes. Katsuki's hand tenses on his shoulder, realizing this is it.
What made Deku use the memory quirk.

Quietly, Katsuki moves to grab the cloth hanging on his towel rack, wetting it with warm water. He takes his time cleaning the caked-on blood and dirt covering Izuku's face.
"There." Their foreheads meet while he cups the cleaned cheeks. "No more hiding from me, Freckles."

"Okay." Two slow breaths carry a slight shakiness. "You asked me if we ever went on a date. Back then, you never called it that, but the night of the attack, there was a re-showing of my favorite movie-"
"All Might Rising." Katsuki doesn't know where the information comes from.

Izuku flinches against his forehead, sees it for what it is; the quirk weakening again.
He doesn't stop like before. "You said we'd bring Eri to ask if she'd be okay with us adopting her. I planned to tell you how I... Kacchan, you're so smart, you probably knew. On our way-"

16
When Izuku starts faltering, Katsuki sharpens his voice to stop the walls from coming up. "Oi. Whatever happened, it's over. The only way it'll fuck us again is if you don't tell me."
"You don't understand," Izuku struggles with his words. "I... almost killed you and Eri."
"You don't understand," Izuku struggles with his words. "I... almost killed you and Eri."
17
It's not what he expects, but he pushes through the initial shock to follow his disbelief. "I call bullshit, Deku. Anyone who's seen you with Eri knows you would never put a hand on her."
"Its because of my quirk that All For One ambushed us."
"Oh, you control villains now?"
"Its because of my quirk that All For One ambushed us."
"Oh, you control villains now?"
18
Despite his snark, Izuku only squeezes his eyes shut. "We didn't have our gear, and with Eri, everything got out of control. She was trying to help, like she did with Chisaki-"
The doesn't remember this, so he stays quiet.
"But then..." The tears start. "You protected us."

19
Katsuki's stomach twists like he's on a ride he needs to get off. A strange throb pulses under the wound over his heart and hip, and he tries to swallow through a lump in his throat.
"You dropped, there was so much blood, and..." Izuku shakes on the sink. "Eri lost control."

"Is that what made her rewind?" Katsuki asks, needing to push forward.
"She did it to keep you from dying, but All For One had someone there to counter it. It reflected back to her, and she almost rewound beyond birth."
He can't think about his daughter going through that.

"How did we make it out?"
"Before they could take advantage of my breakdown, Aizawa came with back up. All For One got hurt, so he retreated." Deku's voice weakened. "But he said he'd always be able to find me through you and Eri. Because of Search, you were in constant danger."

22
"That's not on you, Deku." He shakes their heads together to cement his point. "Burnt Toast is-"
"A monster, I know. But that's the point." Green eyes look at him, full of tears. "He tried to kill you and Eri because he knew the truth. You've always been my weak spot, Kacchan."

23
He's unsure how he feels about the confession, hands dropping to Izuku's waist. Being a powerhouse that never backs down from a fight, he's not used to being a...
His teeth clench. "You used the quirk because I'm a liability."
He doesn't expect a raised voice. "That's not it!"

"Deku-"
"You have always been my backbone. My motivation. My hero. Everything I did, it was knowing you'd never let me fall."
Izuku speaks with emotion Katsuki wishes he understood. There's layers in the hand touching his cheek, pulling their faces closer in the quiet evening.

"But I watched you in the hospital, clinging to life. I knew then my heart will always make you a target for All For One. I had to-"
Izuku hesitates, then rises to the challenge. A hero Katsuki bets he's always been.
"I didn't use the memory quirk because you hinder me."

26
Katsuki needs to be closer, hates his vow not to cross the line when their lips brush. "Tell me why, Izuku."
"I couldn't give up One For All. But I knew you'd never hide from All For One. I couldn't watch you die for me." Izuku smiles through his tears. "Because I love you."
"I couldn't give up One For All. But I knew you'd never hide from All For One. I couldn't watch you die for me." Izuku smiles through his tears. "Because I love you."
27
His hands twitch over Izuku's waist, unsure where the breath in his lungs escapes to.
Katsuki's never kissed this man, never had him underneath him in bed. He's gone much further with strangers.
But Izuku's declaration feels like something he's waited for his whole life.

28
"I love you." As if scared saying it once won't break the quirk, Izuku slides his fingers into the back of Katsuki's hair and professes again. "I'm sorry I love you."
"Don't apologize," he growls, rejects the words. "Don't you fucking-don't let him take another thing from us."

29
For a moment, nothing moves. Their breathing mingles between mouths mere centimeters apart. The bathroom protects them from the outside world.
He pretends they don't have to be heros here. They're just two men who found each other and bound their souls together without fear.

30
There's things he wants to say, but Katsuki hold them back. It's not fair for him to toss around 'love' when he doesn't remember their full story.
No matter how much his body knows the man collecting his broken pieces within Katsuki's arms, he's not who Izuku fell in love with.

Deku swallows, tries to think through his emotions. "Right. We should talk to Aizawa and All Might. Maybe have our friends with Eri help us plan for tomorrow."
When the world wakes up and remembers Hero Deku.
"Not a bad idea, Nerd," he says just to drag out Izuku's smile.

32
The nerd lets out a sigh and moves to lean out of Katsuki's space. But Katsuki isn't done with him, almost tugs him off the sink to keep him close.
"Don't think I'm ignoring what you said." Deku's guilty eyes confirm it's a thought. "You'll get an answer, but from your Kacchan."

33
"I already said it's the same person." Izuku doesn't hold back anymore. "I love every version of you."
Katsuki's past self is an idiot, because Izuku's love spills off him. His voice, expression, and body language begs to be seen. Why did he let Deku think it wasn't mutual?

34
He shoves his confused thoughts away. "Finish cleaning up. I'll grab you some of my clothes, then we'll call the hobo."
Katsuki gets to his room before he pauses. He stares at the bed, knows the power it now holds.
Because when he wakes tomorrow, he'll remember everything.
