Channel A's Heart Signal chronicles and analyzes the romantic interactions of young men and women living in the Signal House, inviting viewers to deduce which pair will form. Through Season 4, the series dominated ratings and headlines, maintaining an unbroken streak of success.
Director-producer Park Cheol-hwan, who followed Heart Signal by successfully launching Heart Pairing last year, earned a win at the 2025 Fundex Awards in the TV Season/Mini Variety category.
Park's nuanced directorial touch across the 'Heart' franchise has raised expectations for Heart Signal 5, his first season in three years. The celebrity prediction panel reunites originals Yoon Jong-shin, Lee Sang-min and Kim Eana and adds newcomers Roy Kim and Tsuki, promising fresh chemistry.
The original panel will draw on viewer data accumulated over past seasons to deliver the dependable deductions fans expect. Newcomer Roy Kim, a singer-songwriter beloved nationwide for songs that spark romantic interest, is expected to make a strong impression in the guessing. Tsuki, a member of the sonically adventurous group Billlie and a recent variety-show standout, should enliven the studio with her candid, playful banter.
Park said he feels reassured that the three founding members are returning for Season 5 after a three-year hiatus. With Roy Kim and Tsuki joining, he added, the panel will introduce new charms as dating-show MCs and heighten the fun of spotting budding romances. The production returns with a more authentic, deeper emotional throughline alongside a new generation, and the team asked viewers to look forward to the series' renewed wintery sensibility.
Heart Signal 5, poised to awaken viewers' romantic instincts after three years, is scheduled to premiere in April.
