I think about Oikawa being able to use and wear make up like, a lot. like when he was younger and grew up with his older sister, he’d always ask her to let him use it too. she would smile and let him put some on, and even though it’d look messy the first few times they’d both have fun with it. he even used to let her put it on him until he finally learned to apply it really well on himself.
he’d wear it when he goes out to the mall with his sister or to eat, or wherever, and he feels super pretty and good about himself.
when he meets Iwa for the first time he’s wearing his makeup and poor Iwa almost confused him for a really pretty girl. Oikawa wasn’t offended, but he found it hilarious because Iwa was so flustered as he kept apologizing.
eventually he invites Iwa over for a sleepover and Oikawa shows him his ever growing makeup kit his sister bought for him. Iwa is pretty impressed, then he shyly asks if he could wear some too. Oikawa is beaming.
they wear it occasionally in grade and middle school, but when they get to high school they both stop wearing it because they suddenly feel super self conscious. they don’t wanna get made fun of by their volleyball team senpais.
then they reach their third year and they go to a party. they debate about wearing makeup but in the end they decide screw it, we’re wearing makeup, we don’t care anymore. it’s been a couple years since they’ve worn any, and they feel so happy because they still look beautiful and they’ve missed it.
Iwa shows up wearing dark eye shadow and cat-eye eyeliner, while Oikawa’s wearing purple lipstick, some mascara and glittery eye shadow. they look amazing and they know it. Oikawa brought a bag with him to hide behind the couch filled with makeup products in case of an emergency.
through the night they eventually run into Mattsun and Makki, and they’re terrified. they’re best friends, but they haven’t told them their little secret that’s right on their faces.
but instead of laughing Makki and Mattsun are just… speechless? they’re not laughing? they tell Oikawa and Iwa that they look gorgeous, they ask where they got their makeup done, and Oikawa just.. wants to cry. he does, and it ruins the mascara. Iwa fixes it for him and Mattsun and Makki are impressed.
they ask if they could get them both to put on makeup for them because they wanna try it too. they happily do it for them; Oikawa is busy applying a pretty shade of pink on Makki’s lips while Iwa is putting cat eyes on Mattsun. they all look good af and they have a fun time at the party.
on monday, they all show up to volleyball practice showing off, and everyone is pretty much in awe because their senpais look really good.
they now wear it whenever they have sleepovers or when they finally start dating.
