-The author clearly has done their research about what life is like for someone who is deaf, as the every day problems Yuki has are not always the types of problems hearing people would think about, such as her setting down dishes too hard (which a hearing person wouldn't do, because the noise makes it obvious you're being too rough with them.)
-Though there is some of the standard conflicts, like love rivals, this is handled in an unusually mature way, rather than the usual dramatic fashion. It makes Itsuomi look like a super good boyfriend.
-A lot of time is spent on Itsuomi's passion for languages and travel. I've noticed the more flimsy manga romances don't really pay much attention to the characters besides their relationship, and as a result the characters lack depth and their relationship feels superficial as they have nothing to talk about except how much they like each other.
If I have any criticism of it, I suppose it would be that I wish a bit more time were spent on developing Yuki's character beyond the fact that she's deaf. Unlike Itsuomi, as far as I've read, she isn't given any hobbies or passions of her own. Though at least she does have the ambition to get a part time job, so at least that's something.
