i think if samatoki had kids, he would try hard to make sure that he was a better father than his own dad was. it would take him years before he could even have a kid. like he would be like an older dad. for reference, both rei and otome had their kids in their late 20's, so if Samatoki had a kid, he would have to be like 32 minimum.

he wouldn't be like his father and beat on his kid, if that's what you're asking. he'd do discipline in other ways away than that. he'd make sure his kid would be a responsible adult who knew how to fend for themselves. idk he looks like the type of guy who would teach his kid how to fight in case he got bullied.

like... "Oi! What happened? ... Ah, schoolyard scrap, huh? Did the other kid hit first? Yeah? Ok... Did you at least win the fight if you didn't hit first? You did? Attaboy!"

idk the point im saying is that he would try to be a tough dad who teaches his kid well while never being an asshole. He would love and care for them in his own way without raising his hand.

personally i don't think riou would go to one himself, but he would support anyone who did go.

i have a couple of reasons.

1: he doesn't do well in crowds in canon. those parades are too loud and overstimulating if he's right in the middle of it so he would rather just keep to himself

2: i think riou is in the closet, at least to most people. it's not that he's ashamed of his identity or something like that, i just think he doesn't feel like it's anyone's business. he's out to very close comrades, but he just doesn't say anything. if he goes to a smaller event like that, he might just go in regular attire with none of the flags and stuff.

sorry if this isn't the response you wanted!!! forgive me lol

OOOOo um i have a couple that i like a lot!

https://archiveofourown.org/works/28297827 this one is really fluffy n cute i love it bunches wahhhhhhh

https://archiveofourown.org/works/38428531 this one is also really nice. op is really good with their characters. they also did this au for them if you look into their acc but it is nsfw so I'm not gonna link that directly so um.......PROCEED WITH CAUTION!!!!!!!!

https://archiveofourown.org/works/52332316/chapters/132387418 here's this one that oomf wrote for me !! (thanks klav!!) read this one and the other fics in this its really nice

Generally, there isn't a lot of samariou fics. if you take out all the poly ships, there's only like...fifty? and if you cut it down for english only it only gets cut down more. its harder to find these gems so i cherish the ones i come across a lot wahhhhhh

I have a couple lol

1: Samatoki has a lot of ships in which his typical interaction cycle involves him either being sarcastic or snappy at people. While I don't necessarily mind that, it does get repetitive and/or gets OOC real fast at times. With Samariou though, Samatoki is honestly at his most mellow. It's such a deep contrast to something like Samajyu, where they're very snappy. And while I do understand that people bond with others by being rude and sarcastic, I would rather see his more mellow side come out. I am a bit of a sucker for the whole "Becomes less crass around S/O" trope lol. Not saying he like turns into goo in Riou's hands lol like no matter how mellow Samatoki gets, he is always gonna be like that. I'm just saying it's a pleasant contrast to his outward personality with MTC (particularly with Jyuto since that's the most visible pairing to others.
I don't particularly like a lot of Samajyu fan content because it gets super OOC n like...very mean-spirited. Some interpretations work really well and i enjoy it a lot, it's just hard to find and I'm not particularly interested in seeking it out.

2: RiJyu is really good i like it i don't mind RiJyu. I'm just more interested in Samariou. I draw RiJyu sometimes i just dont post it sorry 💔

3: MTCpoly is something that I don't really like. I don't like a lot of poly ships in general I'm sorry. I'm not against them, lord knows I had many poly ships back in da day. However, whenever you look up poly content, especially in Japanese, it's very obvious it's about one character having attention by the other two (HamaRi, HamaSa(ma), HamaJyu)
It's either that or like...it's obvi it's a couple +1 which makes me sad. like IDK...in fiction, i don't enjoy seeing a poly ship where it's just like...the main two are the only romantic dynamic in the group and then there's the third who shows up for whatever. Like it doesn't make me feel good...
With MTCpoly in particular, I do have another reason why I don't think all of them together as a romantic couple would work IN MY VISION. i think each of their individual relationships can work as romantic, but I don't think it can work with all of them together. Platonically though? Fuck yeah! if you like MT3, power to ya, it's just not my thing lol

sorry if there's any typos ;;

WAHHH THANK YOU THATS SO SWEET 😭

As for ur question, riou is very much a morning person and samatoki hates that. Riou does stay up sometimes but he prefers sleeping early. Sometimes tho they do silently compromise. Samatoki would sometimes feel Riou's arm wrap around him in the morning and wake up with him, talking with him softly before getting coffee for the both of them. Other times Riou would stay up with Samatoki and smile as he silently enjoys his presence.

Sometimes though...sometimes Riou would wake up to Samatoki already up. Riou would ask when Samatoki woke up, in which he would respond that he didn't sleep at all, accidentally staying up. Then they just spend that time before sunset with eachother.

As for routine i think they're pretty much the same apart from time. Get up, shower, brush teeth, drink coffee, work out, go out for the day. But with eachother it does tend to go by a bit slower, even if they don't mean to do that.

I DO. I think 10 years down the line when they're 35 and 38 respectively, i think life will look basically the same, with the caveat that i think Riou wouldve adapted back into some form of regular life with Samatoki. Like not entirely normal but he lives in a house with a roof now. At this point samatoki wouldve mellowed out significantly from his 20's spunk and now is sorta like a uncle who you call a hardass but is super nice in his own way (he'll still kick ass if necessary tho)

Because of this, he and Riou don't have a standard relationship dynamic. They love eachother deeply but unless if you were direct friends and family, it would just look like they were roommates. Despite their casual approach to dating, even after 10 years they remain affectionate towards each other in ways that satisfy them. Idk MY BRAIN IS BLOWING UP. I saw an artist a month or so ago draw mtc in their 40's and i flipped the fuck out seeing them so i think about da future for them a lot. Thank you for asking YAY!!
