You're writing is amazing!! <3 If possible, is it alright to do something focusing on an embarrassed/shy sidekick that got injured in battle, and has to let the (flirty) hero tend to their wounds/wash hair/feed them because of how weak they are at the moment? Bonus points for a very touch starved sidekick, and some tension.
"Sit." The hero met their eyes. "What sort of mentor would I be without giving you the appropriate post-battle aftercare?"
"You don't have to phrase it like that," the sidekick mumbled. They did sit, though.
"What?" The hero grinned, opening up the first aid kit. "Aftercare?"
The sidekick looked down, horribly aware of the heat radiating off their face.
The hero laughed quietly; warm and fond.
"The injuries aren't that bad," the sidekick said. "I'm just tired." So very, very tired. Their limbs felt like melted marshmallows; pitiful goop.
"Mm, no wonder. You were very impressive out there."
"Just doing my job." They shivered as the hero began to make quick work tending to their minor wounds, touch warm and strong and confident. They tried not to lilt into it. They blamed the exhaustion in the fact that they did.
"And now I'm just doing mine, hotshot."
The hero pressed closer, shifting so that they could take the sidekick's weight. They stroked their fingers, entirely unnecessarily, entirely lovely, through the sidekick's hair.
The sidekick's eyes fluttered closed. A small, embarrassingly needy sound left them. "S-sorry."
"Don't be. You're sweet."
"I think it's adorable." The hero placed the last plaster over a cut on the sidekick's temple. "You never let me look after you normally. I like it."
"Well, I'm supposed to be supporting you...."
The hero pressed a kiss to the sidekick's temple.
The sidekick's eyes, for all of their tiredness, snapped open. They glanced up at the hero.
The hero smiled again. "Kissing it better. Did it help?"
The blush returned full force. "You're ridiculous."
"I could kiss the rest of them too. Just one might be a fluke. It's not scientific."
"So stupid." The sidekick covered their burning face with their hands.
"Don't tease me." It was another mumble; torn between the delicious squirming feeling that the teasing left in them and the sheer horror of it, that the hero might be mocking them.
They didn't think the hero was mocking them, though. They weren't the sort. Did they flirt with possibly everything? Yes. Were they unkind? No. But that didn't make it real. That didn't make the desperate rise of hope in the hero's chest any easier to bear.
"You are cute." The hero did a last check over the scrapes and scratches, before moving. They pulled the sidekick up into their arms, cradling them like they weighed nothing. "My cute little absolute devastation of a powerhouse."
"It was nothing." The sidekick clutched hold, stomach swooping.
"You save them. I save you. It's nothing."
"Hey." Some of the flirting dropped. The hero waited for the sidekick to meet their eyes. "It's not nothing. Thank you."
The sidekick swallowed, but managed a nod.
The hero carried them through to the spare bedroom, and for all of the sidekick's flittering nerves, they were half-asleep by the time they arrived. Sapped of strength and energy. It made it easy to go along with the hero for once, to let them tuck the sidekick beneath the sheets.
The hero caressed their cheek, taking another moment to study them, gaze intent.
The sidekick slid theirs away, breath catching.
"I'm not teasing you," the hero said, softly. "I'm quite genuine in everything I've said or done. I wouldn't tease you. Not like that anyway."
"Get some rest, hotshot. Good job today. I'll be in the other room if you need anything."
The sidekick wanted to stay awake. They wanted to tug at the string of the hero's earnestness, whatever the hell it all meant. Their eyes were already closing again, the room tunnelled at the corners.
Their last act was to reach out, woozy and weak, and take the hero's hand. It felt like the bravest thing they'd ever done. Far bolder than that day's fight.
The hero stopped. They mattress dipped with their weight.
"Okay," they said, stroking their thumb over the sidekick's knuckles. "I'll be here."
And, even when the sidekick woke up hours later, they were.
