Based on the Daum webtoon of the same name by Chon Kye-young, it follows the life of a high school girl in a society greatly influenced by a mobile app capable of notifying whether someone within their vicinity has romantic feelings for them.

In January 2017, Netflix collaborated with Hidden Sequence to produce their first South Korean original series for the platform based on the eponymous Daum webtoon by Chon Kye-young.

Each space was decorated as if the app function in the drama is visualized in reality and gave a romantic experience to lovers, friends, and family who visited the place.

[30] Forbes's Joan MacDonald wrote that Love Alarm gives the familiar romance drama "a fresh twist" by introducing a mobile app and found that "Kim So-hyun is well cast as Jo-jo".

The series is a bit of a Trojan horse for unassuming teen audiences: they might be drawn in by the Cinderella-like love story, but end up learning a lesson about the ills of social media addiction.

Pierce Conran of South China Morning Post gave a rating of 2 out of 5 and said, "There is even less meat to the story than first time around, and some jarring secondary plot lines that try to mix in social commentary are distracting.

"[35] Greg Wheeler of The Review Geek gave a rating of 5 out of 10 and said, "Ultimately though Love Alarm serves up a lukewarm offering that's going to feel colder for fans expecting a red-hot follow-up to what's come before.

The grand success of Netflix's Love Alarm, based on a webtoon from 2019 left fans wanting more drama, romance, and some answers to the fate of the main characters.
