@unknownmat obviously answering this very late, but the two series that I love due to the writing are Otherside Picnic and Dahlia in Bloom.
Dahlia is new to JNC so you can read all of volume 1. Cozy world with snappy dialogue, it's quickly become a favourite of mine.
Otherside has sharply observed characters and the author manages to give the supernatural plot a really distinct groundedness. An underappreciated gem.
In both series, I think it helps that the main characters are a little older than your standard shonen fare.
