Work Text:
It started with a late night mission.
Katsuki and Izuku got a last minute alert to go and deal with some villain off the coast who was threatening to flood the neighboring village.
It was freezing cold and raining heavily due to the villain's quirk, and Izuku's dumbass didn't set his suit to extreme weather protection mode. A mode that Katsuki insisted on having because he knows how weak his boyfriend's immune system is.
But, no. The nerd refused to enable it because he was convinced that he was as healthy as a horse. 24 hours later, he's bent over the toilet with glassy eyes and a stuffy nose. Who's fucking surprised?
When Katsuki wakes up it's 8 something in the morning. He turns slightly to find Izuku resting his head on his arm. Katsuki frowns a little at feeling his forehead still being warm, it seems like his fever didn't go down with sleep.
Katsuki already called out of work for the next couple of days to take care of Izuku. He would've asked Inko but she's busy remodeling her house with his mom and dad. Plus, Katsuki wanted to be here with Izuku anyway. Katsuki, very gently, tries to move his arm from under Izuku's head only to end up being pulled back down weakly. Oh, here we fucking go.
"Mnhm. Kacchan? Where are you going?"
"Gonna get a cold cloth for your head, then make breakfast."
"Can't that wait? Come back to bed.. please."
Katsuki huffs softly, Izuku always gets like this when he's sick. Extra clingy and not wanting Katsuki to move more than 3 inches away from him. And although Katsuki finds it really cute, it also pisses him off. Because then he barely gets the chance to actually do anything.
"If I stay in bed who's gonna make sure you're taken care of, huh?"
"M'fine. Don't need to be taken care of when Kacchan is my medicine."
"Corny as fuck."
"It's true!"
Katsuki lets out a frustrated sigh, "Lemme get up, Izuku."
"Kacchaaaan. Just 5 more minutes? Please!"
"Nope! I gotta do shit, just wait here."
"You hate me." A sniffle, " You hate me and you want to break up-"
Katsuki rolls his eyes and quickly removes his arm from under Izuku's head– giving a harsh pinch to his cheek, "You dramatic little shit. Just let me take care of you."
Izuku peeks one of his eyes open to level him with a glare. Katsuki cackles as Izuku turns over and tries to huff angrily but ends up coughing violently instead.
Katsuki returns later with breakfast fully cooked and plated because he's the best boyfriend in the whole goddamn world. He hands Izuku his plate and watches how he just stares and refuses to pick up his chopsticks. Katsuki sighs.
"What the fuck is it now?"
"Can you feed it to me?"
Katsuki scoffs, "You a baby now or something? Hell no!"
"I'm not eating unless Kacchan feeds it to me!"
Izuku stares straight into Katsuki's eyes with no intention of backing down and Katsuki feels his skin begin to prickle from annoyance. Not because he's annoyed at Izuku's antics, but because of how easy it is for him to adhere to them. Pathetic as hell.
"Fucking– Okay! You better eat every last crumb of this shit or I'm kicking your ass." Izuku instantly brightens and starts to nod with vigor, "I will!"
