This is a spoiler free review for the whole series, up to where it is currently out in English volumes (volume 10). I update it periodically as I don't like rating individual volumes and would rather rate the series as a whole. 

This series is the cutest thing I have ever read! Want a fluffy cute romance with some emotional impact? Read this series! I kick my legs at the romance in this series in every single volume. The female lead being Deaf adds a lot of nuance and depth to the story. The main characters are highly endearing and I love seeing their relationship develop, along with the side characters.
