The five characters show their feelings on their posters using their own lines from the show. Jo-jo, who is unable to communicate her mind because she has a placed block on her “Love Alarm,” reveals her innermost thoughts, saying, "I told him for the first that I like him," which raises questions about who she is confessing this to. Hye-young, despite having an unresponsive alarm, says, “Whether that thing rings or not, it doesn’t matter to me,” expressing his deeper feelings toward Jojo. Sun-oh, saying “From now on, I’ll trust only what your eyes tell me” to distance himself, still shows Jo-jo affection, foreshadowing a more intense love triangle. Gul-mi, who is trying to enter the “Love Alarm” club, says “Who, me? Why? What about me, exactly?” and seems to be unable to hide her embarrassment. Yuk-jo, who is dating Sun-oh but knows Sun-oh still has lingering feelings for Jo-jo, says “I know that feeling of a burning heat. How can I beat that?” and relates to everyone who has ever experienced unrequited love.

The shape of the ring, which shows slightly different variations depending on the character, seeks to catch the eye. The attention will be focused on the expanded story of Season 2, which will show a darker triangle romance and a more diverse form of life and love in a world that has changed so much since the launch of the “Love Alarm.”

Love Alarm Season 2, which shows the inner feelings of five people, will be released March 12th exclusively on Netflix in over 190 countries around the world.

The trailer opens with Jo-jo (Kim So-hyun) narrating, “In this world, you must ring an alarm when you like someone.” Jo-jo, who is dating Hye-yeong (Jung Ga-ram), still concerns herself with the Love Alarm app despite hers not ringing. Sun-oh (Song Kang) appears with a poker face and stares at someone. Though Jo-jo is with Hye-yeong, she cannot hide her complicated feelings for him. Sun-oh's words and actions further complicate the situation. “From now on, I’ll trust only what your eyes tell me,” Sun-oh proclaims to Jo-jo before kissing her.

Following more emotional scenes, it becomes clear that both Hye-young and Sun-oh want to convey their true love for her. The trailer comes to a touching end with Jo-jo’s narration: “Who do I love now?” The love triangle among two men and a woman who want to confirm each other's true feelings will unfold in this season."

The first season of Love Alarm is available to watch now, and the second season will be released on March 12, exclusively on Netflix.
