Naruto would've burned his house down if not for the lucky switch that happened between him and Hinata at just the right moment.
The girl froze when she realized that she wasn't actually combing her hair and was instead watching a kettle fill with water from the sink, only realizing and turning off the water when it overflowed, then wondering where that smoky smell was coming from until she caught sight of the iron she'd lent Naruto laying face-down on the sleeve of a black T-shirt.
He was shorter than she was, she noticed, because though the ironing table she'd lent him was small, it came up to somewhere between his shoulders and chest, where on her body it leveled out just above her stomach. She'd just never had the opportunity to notice before, she guessed, because his volume made up for his size.
After setting down the iron so it wouldn't burn anything, she emptied the kettle a little and set it on the stove, guessing he was about to make noodles and not tea, since there was a cup of cheese-flavor ramen on the counter and her stomach felt empty.
Hinata gingerly picked up the iron and finished the shirt for him, thankful it was black, because there was no noticeable singeing on it from before now. The pile of laundry Naruto was taking on wouldn't last very long if he didn't know what he was doing, particularly since some of the clothes had stuff on them that might warp if pressed against the iron.
She bit her lip (Naruto's lip?) and searched the small apartment for a solution, finally spotting some paper and crayons on a chair.
Do not leave the iron on the clothes while it is on. It will burn them.
When you iron your green and red shirts turn them inside out or the letters will melt.
Naruto blinked when the kettle whistled, needing a second to figure out where he was. He'd been afraid of giving himself away when in Hinata's body, so he'd stayed in her bathroom for the entire time they'd been switched, rearranging the little soaps by the faucet and making faces at himself in the mirror. Hinata's face didn't do 'scary' very well, he discovered.
His stomach rumbled and he ran to make himself lunch, only stopping to wonder what it was she'd done while she'd been here once he'd eaten.
The next day he came to school looking the neatest he ever had, and blushed when Hinata complimented him.
"It was thanks to your note," he explained, smoothing a hand over his shirt proudly, nonetheless.
"You still look really nice," she said, with a smile.
The tips of his ears turned red, and Hinata suddenly understood why people acted like it was so fun to tease others.
