Naaaaah...

Spoiler for my prediction:

I'd assume that if the story goes for long-to-middle-range, the result of this meeting should eventually leave Haruto and Nanami in "more than friends, less than lovers" limbo, with Yuzuki in between to cause trouble.

Face it, Nanami _is_ interested in Haruto, and Haruto _is_ interested in Nanami. However, he's beginning to become very protective towards Yuzuki too, and that's going to cause issues in the medium run.

(That's how I foresee the developments in the near future)
