YOU GUYS ARE NOT READY !!!
Seriously, I have read the whole web novel and this is my favourite yuri, favourite romance, favourite
written sex scenes, flirting and intimacy in media in general. Yes, I like it even better than Bloom into you personally.
This is a really great story, about 95% of it is spent on them in their room flirting too, though there is a TON of inner monologues, that seem to be missing, that is natural for manga, but I think they held back on the first chapter and in the future they might come back to explain why are these disaster level girl failures acting as they do. If you ever get confused by them, hop into the webnovel, it should clear things out somewhat.
I'm really happy with this first chapter, the art is really high quality which leads me to belive they are commiting to this story, anime might be on the horizon in couple of years. I love the expressions cheeky Sendai and sulking Miyagi, they are just how I imagined them. I didn't get the vibe it's much different from WN, but certainly without all that inner monologue, the story starts being more cheerful, comedic and easier to follow. I think that's great, good adaptations have different strenghts and you'll get the full experience only when you see both.
Also, this story is LOOOOOOOOOOONG, this covered about 1/10 of first LN, 3 WN chapters, but there are currently 4 LNs and 340 WN chapters and it's ongoing, LN adaptation might change,cut out, rearrange and smarten up some stuff and manga probably follows that, but the point is that this story is going about their relationship the long route, trust me.
The thing that gripped me about Shuukura is how quickly things get spicy, the feet licking is great in media res start, but things certainly don't slow down after this. The thing that kept me reading is how well their relationship progressess, despite their relationship not progressing by certain metrics, but honestly they get much closer than any fictional couple I've seen ever.
(Also, please, mr. translator, could you change Hadzuki into Hazuki, every translation I've seen uses it so this was a bit jarring for me, but granted idk japanese so maybe your take is more accurate? It's just that I've seen Hazuki multiple times in anime and manga and it rolls of the tongue better, so I got used to it, I've looked into some character databases and there are ton of Hazuki's, but almost no Hadzuki's)
