osamu realized that suna was down bad for you very early on in your relationship.
you see, suna was a bit of a fickle guy. an "i do whatever the hell i want" kind of guy. a lot of his actions had no rhyme or reason and he did them based purely on amusement or simply "why not?"
for example, he had a little game he liked to play that osamu had no idea how suna got the idea for. whenever he'd meet unimportant strangers like baristas, cashiers, people on the street, he would completely lie to their faces about everything about himself.
he was not suna rintaro and he did not play volleyball. he'd give them different identities each time with a completely straight face like this was completely normal.
he'd tell the barista that he was in college and currently pledging to a fraternity. he'd tell the sweet old lady in the park that he was a single father of two trying his best. he'd tell the cashier that he was an italian fashion designer in a really oddly perfect accent.
"why d'ya do that?" osamu had asked him once.
"just 'cos," suna had answered nonchalantly, "why not?"
that was the thing about suna. he was hard to pin down.
why did he do this? for fun.
why did he do that? he just felt like it.
he was like a gust of wind; a wave at your feet. he did as he pleased when he pleased.
none of suna's "identities" had a particular pattern. he gave the strangers completely randomized names and incredibly detailed life stories that he would literally come up with on the spot.
one day, his name was akane, and he was studying biology at fukuro uni. he was born in okinawa, hence his dialect.
another, he was hizashi, and he had three beautiful baby girls that he was mighty proud of. they were all young, so they were quite a handful, but his mom was helping out, and he couldn't be more grateful for his family!
the next, he was kaito, and he just moved from his family's rice farm in akita. his family also grew fruit, like pears and apples. he moved to the city to try and fulfill his dream of having an acting career!
seriously, there was no point trying to make sense of him. osamu began to wonder if suna was some sort of social experiment bot put out by the government.
however, at some point, right around when you and suna had started talking, osamu began to notice something. suna's actions usually had one pattern: that there was no pattern. however, he began to notice that one was actually forming.
his identities and stories were still random, but there seemed to be a constant:
even as watari, the aspiring engineer, he had a new girlfriend who's not good with mornings.
even as miyano, the very young grandparent, he had a lovely wife who liked to surprise him with backhugs.
even as tooru, the nice young man who volunteers at the animal shelter, he had a girl he was talking to that had the cutest smile.
every identity, no matter what age, background, career, preference, whatever, included a girl who sounded exactly like you.
it was then that osamu realized.
it didn't matter what form, identity, timeline, or universe suna had randomly picked that day for his own amusement.
he would find you, choose you, and love you in every single one.
notes: i feel like i saw something similar like a few years back but it was BL not 'x reader' and that was what inspired this but i cant find it. i dont know if im crazy and thought that up on my own or if im just stupid but if you see the original or if you're the original, let me know and i will credit you!
