Just like Suzutsuki I'm not big on fanfiction so I thought I'd just check your story out - I reached the end before I knew it.
You have a very nice style - even inspired at times - and it's like you said: your love of the source material really shines through and I enjoyed that. I especially liked how you tied Nozomi's special blend of fortune telling and intuition into your storytelling. Also you did a marvelous job on the build-up.
I'll leave it at that, I don't mean to write a review or repeat what Suzutsuki said, just wanted to say I loved it^^
(Nozomi tending a café, waiting for her love to "come to fruition" - I couldn't help but be reminded of Fragments of Love, just my imagination?)
Now to find "a sequel" to your story with some impish, mischievous Nico x Nozomi ...
