The first time I picked up a library copy of 'Moby-Dick', I nearly put it back because the TOC was just chapter numbers. Then I grabbed a newer annotated edition where the contents had these little descriptive phrases – 'The Ship', 'The Whale', 'The Chase'. It wasn't just a map; it was a promise. I ended up reading the whole thing, partly because I'd peek ahead at the titles and get curious. That's when it clicked for me.
A table of contents can absolutely change how you read a serialized web novel, too. If the chapters are just 'Chapter 1', 'Chapter 2', it feels like a slog. But when they have titles like 'In Which the Heir Is Disinherited' or 'The Tea Shop Incident', you get these little hooks. You start anticipating specific moments, flipping back to remember when something happened. It turns reading from a passive activity into a more active, almost participatory one. My reading speed on serials with good chapter titles is always faster because my brain gets a reward just from checking the next heading.
