Oh, the dreaded "Sorry, I have to go". Hopefully, they will actually manage to talk it out before they graduate and not avoid each other for a while, as it tends to be in those stories. If she didn't run away, they could probably talk it out within 15ish minutes, since Ayaka knows that "friends" is not actually what she is looking for and Sora never actually wanted to be just friends, so they just have to figure out what they both want and it's a final straight for the happy ending (or at least a happy beginning).
