For reference, I'm reading this on Crunchyrolls library as if you pay for CR, it's free there to read (I'm in the UK, not sure if this is a geo thing). That is worth noting as it makes the barrier for entry basically invisible.
Another note: If you've seen the anime, give this a shot. I really didn't like the sexual undertones in the anime and I never got that vibe from the manga. These are school kids ffs.
Once I read a few chapters I realised the charm and found it to be a really fun, simple, cute slice-of-life manga that's become something both entertaining and relaxing. There are very few mangas that actually relax me, but this is definitely one and it makes me laugh, too. The amount of charm created by these characters with little to no text is, frankly, astonishing. For that alone this deserves credit.
As noted elsewhere the art style is realistic, the girls are all somewhat realistic looking, not hyper-thin with massive busts. In fact very little here seems to be done to purely attract readers, there is a vibe this manga has and over the 91 chapters I've read it's only gotten more consistent.
All things considered this is worth a shot for anyone who likes SoL stuff.
