I disagree, I believe that the idea was to put up this barrier as a use in order to understand the real need for mutual relationship between the people. While they act independent, that doesn't make them different from any other human in the fact that they still need people to support them. I think while the core ideas of both Hanako and Emi were similar, I found that it was a very different experience. With Emi, I found more frustration with how she acted, while with Hanako, I only had a want to help. Emi's route was overall strong, but I think that Hanako had a much more powerful confession.
