Common fanfic tropes can be things like 'hurt/comfort', where a character gets injured or is in emotional pain and another character helps them heal. Another one is the 'secret identity' trope, where a character has a hidden side or identity that's revealed later. There's also the 'friends to lovers' trope, where two characters who start as friends develop romantic feelings for each other.
One common trope is the 'what if' scenario. For example, what if Sleeping Beauty didn't wake up from the prince's kiss? Another is the reverse roles trope.
