The theme is good, but several things about this manga seemed slightly off to me. I love how passionate the two main characters are about their profession -- to the point that they'll even break gender norms in order to be able to pursue it -- and I love that there were no hints of romance or BL despite there being ample opportunities for both, but the praise ends there.
First of all, this is the kind of manga which is too serious to be a comedy, but too far-fetched to be a realistic drama, and therefore fails to deliver 100% on either. A conflict pops up, and is resolved within a couple of chapters, with little to no foreshadowing as to the future consequences of said incident. The characters are not very well developed beyond the dancing aspect, which is a huge let-down because they're quite likeable. And how on earth is Haruichi and Yuri planning to continue dancing together when Haruichi has such a huge "weak point"?
My next (and bigger) complaint is about the ending: It would have been much better if the final half of the final chapter had not happened, and the two dance partners had walked away from each other having gained valuable experience and encouragement to pursue their respective futures -- perhaps with a promise to meet and compare notes on each others' progress somewhere down the line. The need for a picture-perfect happy ending caused the author to forgo a more meaningful conclusion to her characters' journey, and I believe that was a huge mistake on her part.
Perhaps if it had been twice this length, there would have been more room for improvement. As it is, I recommend Coda for a quick bit of fun and stress-relaxation, but don't expect anything too spectacular.
