Kirishima's roots were starting to come back in, he'd let them grow a little sometimes, but now it'd gotten to be too much, the main problem being, he couldn't actually be bothered to dye his hair, so, he chose the obvious and best choice, make you, his lovely most favourite-est person in class, dye it for him! after actually thinking about his options he trusted you the most anyway, so it wasn't a hard decision, so here he was, excited sweet grin as he held the bottles of hair dye and you set down towels in your bathroom so you didn't stain things

"Super cool of you to dye my hair!" Kirishima chuckled with a little hum, he always liked you
