Viewers see the unedited live feed of the participants and make predictions about who is likely to be building a secret love affair. The show emphasizes body language, slight self-deprecating looks, and other hints of romantic attraction, which make it outstanding among other, more exuberant dating programs.

Franchise Strategy: Heart Signal and Heart Pairing Alternate
The producers have explained that the future Heart Signal and its sister program Heart Pairing will have an alternating release strategy. Since Heart Pairing premiered the show in 2025, 2026 will be the year that the Heart Signal will be back, giving the audience a new dose of the franchise every year without overloading.
The given strategy enables each series to shine and capture the attention of the audience to maintain their interest in the Heart brand.
Why It Matters
Heart Signal has, since its debut show in the year 2017, garnered a cult-like following not only in Korea but also in Asia. It has the emotional realism and slow-burn love stories that go well with a soft pace, which makes it exceptional in the reality dating genre. Past seasons may be heralded due to the number of meaningful connections, sincere talks about dating, and even turning their cast members into social media celebrities.
As the world gets increasingly interested in K-content, now returning Heart Signal is another first in the history of Korean reality television. The fifth season is highly anticipated, and fans cannot wait to have another group of aspirants explore the dating world in a situation that is relatable and insane at the same time.
