It's not reinventing the wheel: it's your plain vanilla wholesome school romcom SoL.
No frivolous drama, no pointless turnarounds, just boy loves girl, girl loves boy, story progresses in a cute way for them to be together forever in the end.
There's only two characters, and they're well developed enough so you can take a liking and relate to both somehow. You've been a teenager, you've been in their shoes.
Art is really something else and makes the show even better. We can see Akino Sora really put their heart into this work.
It's a short manga so it makes for a good afternoon or evening read for when you're feeling down.
