ill try this out

1. kohane rui friends. in the world where vbs meet wxs formally, they weirdly get along and kohane sends him pics of pearl and he loves her very much. they are friends

2. when they were young the tenmas would play stories and tsukasa did story abt a princess, clearly saki, and a prince, but saki went mmm no i want a pretty princess, and tsukasa as the hero went ill take the prince instead then!! later theyd realise this Meant something

3. toya and kohane go out sometimes to the arcade and shes getting better at it! she wants to surprise an with her shooting game skills, which toya is a very good teacher of

4. ichika teaches nene a bit of guitar in return for singing lessons, and shes a bit clumsy but she isnt bad! and nene tried to teach ichika how to act once but she was so wooden nene called it off

5. kohane has a fondness for idols and has gone with minori to see asrun in concert before! does she know in canon that an and haruka are friends yet? i think shed lose her mind

6. akito never liked idols that much but i think hed probably find kohane watching a mmj livestream and watch over her shoulder for a while and chuckle a little bit at airis tsukkomi bits, hed be like "yeah she can stay"

7. kohane did her very best at the miya sports event and i know that an wouldve been there to cheer her on. toya and akito too. toya is polite and akito would be like "go girl ig" until she overtakes someone in a race and then hes with an screaming LETS FUCKING GOOO HAMMYYYY

8. honami uses petnames with leoneed i knowww she does. saki likes it when she calls her sweetie. then she fucks up and at kanades she calls her "honey" and shes Mortified and kanade nearly falls off her chair

9. tsukasa is very musical just as a person. he loves to sing to himself and hums all the time! always listens to musicals on his way to school, and hes very exciteable when it comes to his favourites which he can go on about for hours

10. akito has coeliacs *pushes him down the stairs*

11. rui fucking loves a baby animal... just a little guy... little fluffy fellas. likes to pet. he deserves pet ferrets

12. rui also knows a lot about flower language and emu is always pick stuff off the ground and going RUIKUN WHATS THIS MEAN :D and hes like, emu sweetie thats... thats grass. but hed make something up anyway

13. haruka and an are both gushy types canonically, so i think they have a routine where minori or kohane will do a cute thing and they have to tell each other about it in detail and the other ones like mhm mhm. yes

14. an and kohane now teach each other about brewing after kohanes secret lessons from meiko and they have little brewing dates and they send each other stuff about it too

15. rui is really good at cool nail art and tsukasa absorbs the knowledge from him to pass on to saki. but hes not as good at it himself so he gets them in contact and they share tips and rui does sakis nails for her before leoneed shows

16. everyone in wxs does their own makeup for shows! nene and emu dont really wear makeup casually, rui does, but tsukasa liked to specialise in how to do show makeup specifically, which is a cute parallel to saki learning how to do gyaru makeup i think

17. all of vbs are decent to pretty good cooks, though an is the best at making desserts which is endlessly funny to her bc she can bribe akito with pancakes so easily

18. airi got a lot of cat plushies from fans during her idol days, she is not immune to soft kitty. shizuku buys her every cat shaped thing she sees when she goes shopping
