I feel like this manga can't decide if its going go be the light version of Dare demo, or a knock off of Keikenzumi ( so far more of the latter than the former)... It's not terrible, but the very rapid thematic shifts (and the red flag characters and mountain of ready to serve drama from the "backstory") give it too much of a sense of tension for me to call it straight "fluffy".
Seems to be headed right down the middle. It's covering enough of the same territory as the former that you get some weird bleedthrough if reading them both simultaneously (e.g., forgetting that this FL is actually weak to love and this ML is struggling with issues preventing him from jumping in feet {or dick} first like the other guy does).
It also does hit like KimiZero in some significant ways but diverges dramatically here in that both leads are way more proactive, there's a secondary couple already in place providing examples both positive and negative to advance the main couple and, most importantly, there's no real antagonist character dragging development down.
(There's also quite a bit of overlap with It's Not Meguro-san's First Time, but the MCs here start out, surprisingly, at much healthier emotional locations. Relatively speaking, of course.)
I like that it's its own thing. It can be "fluffy", silly, dramatic and maybe, at times, a bit uncomfortable. My favorite titles are good at putting a unique touch on that recipe for real slice-of-life.
