WHY THIS WORKS ON KU:

• The flip is a documented demand signal without supply. Readers in 2026 are specifically naming "grumpy heroine / sunshine hero" as what they want and cannot find — not as a predicted trend but as a named, waiting readership. The gap between stated demand and available inventory is the clearest commercial signal in Regency romance right now. This concept is positioned to close it first.
• The "he falls first / reader knows before she does" structure is the read-through engine at the micro level. Every scene accumulates evidence — his unfinished sentences, the frequency of jokes in difficult company, the way he deflects questions about himself — before Harriet has the vocabulary to name what she's observing. This creates the specific yearning that BookTok's slow burn cycle rewards: not "will they get together" but "when will she let herself know." That question is personal. Personal questions convert.
• The Regency setting keeps the core KU historical romance audience while the trope inversion differentiates sharply. Rules for Ruin has the heroine energy but not the dynamic. KJ Charles has the dynamic but M/F is untouched. The position is open.
