THE SECOND season of the Korean romantic drama Love Alarm opens with a twist caused by an app upgrade.

The show revolves around a fictitious mobile app, Love Alarm, which sends the user a notification when someone who is romantically interested in you appears within a 10-meter radius. Love Alarm Season 2 starts four years after the release of the app, which has been upgraded. Love Alarm 2.0 alerts users a list of people who are likely to like them in the future and vice versa, and is now equipped with a “shield” function that allows users to hide their feelings. The season revolves around the romantic entanglements this causes for Kim Jo-jo (Kim So-hyun), Lee Hye-yeong (Jung Ga-ram) and Hwang Sun-oh (Song Kang).

Directed by Kim Jin-u, it also stars Ko Min-si, and Kim Si-eun.

“Jojo used to be very defensive so she was wary about her feelings being exposed to others. She was afraid of other people knowing how she felt which led her to use the shield function on the love alarm app so that no one knows how she actually feels,” Kim So-hyun said about her character during Netflix’s virtual media launch on Mar. 8. She added that the shield function will lead her character to undergo personal growth.

“The character (Sun-oh) is someone who does not ring other people’s alarms, but his alarm gets rung,” Song Kang said of his character. “While someone’s feelings may not be the same, and when you have feelings for someone [that is] it’s not reciprocal — sometimes unrequited love is bound to be really sad.”

“In the second season, as you know the characters are affected by the new and updated version of the application. With the app (upgrade) 2.0, there are decisions that you are informed of through the app…,” director Kim Jin-u said of the new season.

“I wanted to portray the process of how and what kind of decision these characters will make while being loyal to each character’s personalities that were established in the first season,” Mr. Kim added.

The second season of Love Alarm premieres on Mar. 12 on Netflix.  Michelle Anne P. Soliman
