yess it's minimal but midori and sora have interacted! the list would be:

• home party (! era), that one was sort of minimal for the two but it's a cute story and they play games together with tori and shinobu

• the rest is !! era. a big important one is midori's 3* fs story, Making-100-Friends-Project, where hinata hangs out with midori to be friends and then calls over mitsuru and sora. i absolutely adore this midori story and it's a must read!!

• next is The Young Master's Moving Out (yuzuru 3* fs story), where they're shown to play a game together (with tori). super cute!!

• there's Our Trip In The Future, featuring 2-A class (which has sora and midori)

• another cute short one is Tiny Universe with hinata too (just the first half)

• midori randomly gets dragged into ibara lecture in Mellow Tactician (ibara fs2 5* story), but interactions are minimal there

• another story that has 2-A (therefore midori and sora) is tsukasa's fs2 5*, A Friend, A Detour, A Way Home, but interactions are extremely minimal

my top three picks for midori's cross scout were hinata, sora, and hiiro (in no particular order), and i had some "if only" choices like mitsuru or mao, which i just knew wouldn't happen as he's already been a 5* pair with them before LOL. and i was really shocked to find out it's midori/sora because i thought they wouldn't repeat unit combinations (since natsume/shinobu happened). i'm super duper happy 🥺🥺

i'm not sure if the new characters are even counted for cross scouts (though it'd be cool), but i'm also excited for the eventual midori and yume story and i can't wait for it... i just know they'll get something together eventually even if not right now!! (also i think your message got cut off at the end?)
