Love Alarm is a South Korean romance drama series set in a world where a mobile application has become a significant social phenomenon. The technology functions by alerting users whenever someone within a 10-meter radius harbors romantic feelings for them. While the application is widely used to gauge popularity and test romantic connections, the narrative centers on a high school girl named Kim Jojo.

As the story progresses, she navigates the complexities of young love while simultaneously coping with personal adversities. Her life becomes increasingly complicated as she finds herself caught in a love triangle. The series explores the impact of this technology on human relationships and personal identity, following Jojo as she experiences the challenges of adolescence in a society heavily influenced by the constant digital notification of others' affections. Based on the Daum webtoon by Chon Kye-young, the show examines the intersection of modern technology and human emotion, highlighting the tension between authentic connection and the digital measurement of love in a world where everyone is connected by the ringing of their hearts.
