Hermione never told Harry that she'd fallen in love with him. (Post-DH angst.)
From the Unofficial Portkey Archive: https://portkey-archive.org/story/8117/
Unfortunately, this fic violated Portkey rules so I decided to take it down. You can find it under the same penname at fanfiction (dot) net; the only reason this note is here is so the reviews won't be deleted.
Thanks,
