What are your favourite story tropes?

It was hard to pick a tag for this post because Movies & Shows also applies, but this will do.

Even if sometimes they're seen as lazy writing and can definitely be misused or overused, every story out there makes use of established tropes in one way or another, and pretty much since the widespread use of the internet they've been even more under a spotlight as amateur writers make heavy use of them as ways to promote their work (yes this also means tags for cringy fanfics despite the way I've worded it).

So I come to ask you, with the help of the anonimity afforded by reddit to allow for as much sincerity as possible: what tropes, big or small, simple or complex, clean or kinky, mainstream of niche, cool or embarrassing do you enjoy, be it on amateur websites or at a fancy book shop browsing from famous career authors? Even if you don't know what the common name for a trope is, I still invite you to analyse the common threads uniting all or most of your favourite stories.

And as said at the top, films and TV shows also apply, as well as videogames and all other forms of storytelling I didn't mention.
