I remember stumbling upon this adorable fanfic titled 'Chocolate Snowfall' on AO3 last winter. It explores Hori and
miyamura's first Valentine's Day as an official couple, with Miyamura secretly learning to make chocolate from Toru. What struck me was how the author captured Miyamura's nervous energy - his trembling hands while wrapping imperfect heart-shaped chocolates, mirroring his 'Horimiya' character growth. The fic cleverly incorporates Izumi's teasing and Yoshikawa's misguided advice, creating that authentic school festival atmosphere we love. My favorite part was Hori finding flour fingerprints on Miyamura's neck, realizing he'd been baking all night.
The story diverges beautifully from canon by having Souta accidentally swap the chocolates, leading to a hilarious classroom scene where Remi almost eats Miyamura's confession chocolate. It's these small, human moments that make fanfiction special - expanding 'Horimiya''s world while staying true to its slice-of-life heart. The fic currently has 12K hits, proving how hungry fans are for these tender side stories.
