Hollywood horror movies often use romantic relationships as more than just a subplot; they serve as the emotional stakes that make the terror meaningful. While horror is primarily designed to elicit fear, the inclusion of romantic storylines provides a humanizing element that grounds supernatural or slasher threats in reality. By examining the evolution of these tropes, from the "Final Girl" dynamics to the "toxic love" of modern psychological horror, it becomes clear that romance in horror is frequently used to explore themes of vulnerability, betrayal, and the lengths individuals will go to for those they love.
