This manga is a bit cheesy, but I sure have enjoyed it so far. Both leads are nice to each other, there is steady relationship progress and a ton of sugar.

This is a pretty well written manga about a loner guy that hooks up with a cute girl in class due to a punishment game. He overhears the punishment game itself, and is prepared to be made fun of. However, when she was confessing to the MC, the MC shields her from a falling bucket of water. Resulting in her actually falling for the MC. They're both shy types and a lot of their firsts are shared. Its very enjoyable to watch them grow their relationship together and overcome obstacles in their relationship as it progresses.

Art is pretty good but not the best art I've ever seen.
Jokes are funny and sometimes cute.

Only real flaw is that you'd expect their shyness to hold them back, but they seem to have moments where they have courage and do some pretty embarrassing things while blushing furiously.

And even funny!
I read a random chapter (the one where she's making lunch) and just had to read the whole thing. Then it was so so ridiculously cute I just had to read the LNs.
The manga is a good adaptation, definitely, and my thanks tot he translators. I'll say the LN is just as good but also has more cuteness to it because you get more of their thoughts (it switches between PoVs, like the manga's extra chapters) and more of what they're feeling.
This series is fun, man!
