While it might not be groundbreaking story telling, it's a good read and the characters are very like-able. The best part of it, for me, was the fact that the main couple actually get together and the story continues to show them behaving as a couple. And (so far) it isn't overbearing with melodrama like some relationship-based stories; the character interactions are sincere and it's easy to root for them.
The communication between the two leads is another strong point of the manga, it doesn't beat you over the head with plot lines based on misunderstandings that could be cleared up with a simple five
minute conversations. Going from strangers to friends to a couple is an interesting enough transition without unnecessary angst, and this story tells it well.
The art isn't really to my taste, but I don't think it detracted from the experience.
