I see this as a good thing. Sora is increasingly at odds with her own image of how she thinks Ayaka views their relationship. She clearly wants to be more than friends with Ayaka, but thinks that her feelings are unrequited. When Ayaka acts like they're more than just friends, but still verbally maintains that they are, Sora is confused, upset, frustrated. I do believe we're seeing the start of a conflict that'll get the two of them to confess their true feelings clearly, or at least I hope.
