Love at first sight is an emotion and a literary trope in which a person feels an immediate and strong romantic attraction for a stranger upon first seeing or meeting them.

Love at first sight is a personal experience and a common trope in literature in which a person, character, or speaker feels an instant, extreme, and ultimately long-lasting romantic attraction for a stranger on the first sight of them. Described by poets and critics from the Greek world on, it has become one of the most powerful tropes in Western fiction.
