After reading a few chapters of Freesia, I am really confused about Higuchi. Is the Higuchi in the coffee shop only an illusion, or is she the real one?

Please explain because I am really confused about Hiroshi and Higuchi,

Being confused is part of the Freesia experience. Just accept that you're confused and keep going. This sort of confusion will happen quite a bit - it's difficult to tell what's real and what's hallucination, and it doesn't really matter if you can tell or not for the most part.

So your telling me I have to suffer through this until the end? Dammit it doesn't make any sense!

Things I enjoy:

1. Badassery. I love being, doing, and living it. I also enjoy seeing it as it usually makes me cry man tears.
2. Badassness.
3. Badasses.
4. Badass mofos.
5. Manly badasses.

Things that I hate:
1. Wimpy protagonists.
2. Girly protagonists (if they're men).
3. Douchie protagonists.
4. Idiotic protagonists.
5. Over-the-line rude protagonists.

It would be nice to have some spoilers regarding this manga because honestly, it scares the crap out of me. So I'd like to know a bit more about the story before I finish all of it.
