This emoji goes beyond the simple act of 'reading' to symbolize 'story' itself. It's sometimes used like an introduction when starting a new story, like 'Once upon a time,' or when revealing an interesting secret.

It's particularly popular in the fantasy genre as an icon for a magic spellbook or an ancient prophecy. It's also used to metaphorically express that a new chapter in life has begun. With this single emoji, you can express both intellectual exploration and a world of mysterious adventure.
