After a year of living and working together, their friendship turns into something /more/.
An accidental "I love you" that gets returned without thought. Forehead kisses when the other heads in on the opposite shift.

Soon, two bedrooms becomes a shared bedroom & an office. Without even talking about it properly for months, they've already fallen into a relationship.
When asked by friends and co-workers what they are, Izuku always answers, "He's my Kacchan."

After 3 years, Deku & Dynamight file with the commission to become a hero duo and soon after, they open their own agency.
Which was amazing! But the only place they could afford was far from their roots. In the northern part of the country.

Katsuki has no problems. As long as Izuku was with him, he had a purpose. Keep the nerd safe and happy.
Izuku has a tougher time. He's always been a Mama's Boy and not being able to continue their weekly dinners at the Midoriya household takes its toll on him.

It's even worse the first time Izuku gets sick. Like really sick. Body aching, hacking cough, upset stomach, super stuffy with a fever kind of sick.
7
Katsuki has never had a great beside manner. But he knows when to bite his tongue now, instead of saying "suck it up, you cry baby."
He tries to comfort Izuku the best he can by making sure his boyfriend always has water and meds within reach.

He warms his palms with his quirk to help alleviate the aches and chills. Still, it breaks his heart when he comes home from patrol to hear Izuku crying over the phone to his mom.

"I w-wish you were here...no, no it's too far for you to travel... but it's not the same. Kacchan is so g-good to me and I feel so stupid for wanting my mom and-I know."
Katsuki sighs and gets to work in the kitchen, pulling out a recipe book.

It's well worn, well loved, and filled with handwritten recipes all the way back to his great-great-grandmother. Unbeknownst to Izuku, Katsuki has some of Inko's recipes in this collection as well. Like her Katsudon. And the one he pulls out from the little clear pocket.
11
It was quiet in the bedroom aside from a coughing fit, and a few moments later, Izuku padded out in full sweats, shivering like it wasn't 80 fucking degrees in their apartment.
"Kacchan? How long have you been home?"
"Kacchan? How long have you been home?"

"You sound like shit," Katsuki huffs. "Get back in bed and I'll bring you something that will make you feel better."
"So bossy," Izuku croaks, but still returns to the bedroom.

By the time Katsuki enters the bedroom, carrying a tray of warmth and goodness, Izuku is half asleep.
Carefully, Katsuki sits on the edge of the bed resting the tray on his lap. He reaches out and cards his fingers through his boyfriend's hair. Izuku is sweaty but not feverish.

"Hey, you need to eat," Katsuki tells him.
"Even though I'm stuffed up, I can tell it smells good," Izuku responds groggily and sits up. "What did you make?"

"Okayu with scallions and a soft boiled egg. There's nori on the side of you want it."
Izuku's eyes widen, glistening in that way they always do, even if they're a bit foggy from sickness.
"My mom always makes me okayu when I'm sick."

"I know," Katsuki says, placing the tray on Izuku's lap. "I heard you on the phone with Auntie when I came home."
"Oh." Izuku's shoulders sag. "I'm sorry. You weren't supposed to hear-"
"Shut up, Zuku. I may not be close to the old hag, but I get it, okay? I'm not your mom."

"No," Izuku says. "But I'm still glad I have you. I love you, Kacchan."
"Yeah, yeah. Eat."
Katsuki picks up the spoon and shoves it in Izuku's hand.
"Yeah, yeah. Eat."
Katsuki picks up the spoon and shoves it in Izuku's hand.
18
That earns him a hint of a smile. Izuku hums as he gathers a portion of porridge with runny egg and scallions. The first bite has him pausing, spoon trapped between his lips and eyes watering.
19
"Shit, not good? You gonna puke? Should I get a trash can?" Katsuki scrabbles off the bed.
"No. It's-it tastes just l-like Mom's!" Izuku practically sobs as he goes on for seconds.

Katsuki relaxes with a smile, selling back on the bed. "Well, I fucking hope so. It's her recipe."
"When did you... never mind. You've always been sneaky asking Mom for her recipes."
"When did you... never mind. You've always been sneaky asking Mom for her recipes."
21
Izuku almost finishes the entire bowl before he declares he can't eat anymore. He settles back against the pillows, eyes heavily lidded and a soft smile on his lips.
"I really needed this, Kacchan. Thank you."
"I really needed this, Kacchan. Thank you."
22
"Heal up, okay?" Katsuki leans forward to press a kiss to his forehead. "Love you, Nerd."
"Love you, too." Izuku mumbles sleepily.
