they are FREAKS and i do not know what the hell they will give us in the next story. in general, there is a multitude of possibilities that valk can throw at us that they can do in the canon verse for the next event. again i don't even know what to anticipate for the next valk event ALTHOOOUUUGH i do hope we get some insight into the little freak mika was when he was younger/POSSIBLY more ex-valk mika. my prediction is if we do not get mika 5* for christmas (shuffle or unit event), there will likely be something relating to ex-valk coming out when seishonen gets added to the game in january (i hope). i really really want more backstory on mika and i think there has to be more reasons he's a little freak creature in game rn. as previously established, i am delusional and praying that mika getting more development

now as for my personal headcanons of them with each other,,.,.,.... i have thoughts. these are just my headcanons and thoughts obviously

big fan of corsetry/them having sex bent over a table or surface and holding them by the strings of the corset. i have had this idea in my head for a while and it can work with top mika or shu but i have a preference for top shu with this.. him dressing mika especially and giving him "maintenance" like this :mmmika:
personally i think shu gets tipsy easily. that man will never hold his alcohol well in any universe in my head beyond half a glass of wine or champagne. saw this art the other day of kitty mika kissing tipsy shu's neck and it had me thinking of drunk shu and the possibilities.. feel free to also give me input on drunk/tipsy shu i would like more thoughts
i think their jealousy and possessiveness over each other obviously builds tension, especially when characters are suddenly too affectionate with shu/mika in front of the other. why else did mika and shu wear turtlenecks/mocknecks for their winter casuals (it's because it's cold out, but let me have this). in general, whenever a character wears a turtleneck in an outfit, i like to imagine a scenario or two with them trying to cover up hickies/love bites underneath their clothes. i also like to think that shu will design outfits for them that hide said love bites
mika getting turned on by shu taking his measurements. possible future one shot i may write now that i think more about it.. he suddenly starts shaking and getting flushed and making small noises because shu is gently touching and brushing over his skin accidentally and it's making the freak come out after they've been apart for a few months (touch starved)
on a similar vein, i think their first night together after long distance.. everyone stay 50 feet away from their room RN!!!!!!
i would like to think of mutual stalking shmk but canon has shown us that is not entirely a possibility but. i can very certainly dream. its just something i've been thinking about a lot more

i think they both also have more niche things they're into during sex, i still have to collect my thoughts on them but. you just KNOW in your bones they have stranger ass things theyre into

i hope this was okay and thank you for the ask anon ;v; i don't have too much written down and most of this was scooped out from the depths of my brain on the spot, i've been trying to give it more thought since you left this!!!!!
i've been working on a few one shots here and there that take place in the canon ES verse, but i just know that i tend to make AUs because i get to take more creative liberties/risks, but i love them in canon and in any universe so badly it hurts. shmksh brainrot 4ever🫶
