Trying to pull together a list like that can be a real challenge because 'complete' is so subjective with fan content. Those scenes get scattered across forums, tumblr sideblogs, and locked twitter threads. I spent ages looking for a definitive one for 'The Wicked King' dynamic and never found it—every list was someone's personal curation with different inclusions and ratings. What helped me was searching for power imbalance as a specific tag on certain bookish websites, then cross-referencing the comments. The comments are where people drop chapter numbers and argue about whether a scene qualifies as 'spicy' or just tense. You end up building your own list, really.
Also, the definition of 'powerless' shifts a lot. Is it magical suppression, social hierarchy, or emotional vulnerability? That changes which chapters people point to. My advice is to lurk in the dedicated subreddits for dark romance or paranormal romance, use the search function with the book title plus 'chapter list' or 'scene breakdown', and save the posts that seem most thorough. Even then, expect gaps and disagreements.
