Channel A’s dating reality program, HeartSignal 5, took an unpredictable turn with the arrival of a new housemate. In Episode 5 broadcast on the 12th, the so-called “Me Ggae Girl,” Choi Min-yoon—the last female housemate—joined the house and completely shook up the love line within the Signal House. At 26, a freelance graphic designer, Min-yoon grabbed the room’s attention in an instant with her bold charm and a no-nonsense remark: “My ideal type is decided in three seconds.”
The first 1-on-1 date partner Min-yoon chose was Park Woo-yeol. Park Woo-yeol won over Min-yoon’s interest with a witty answer, saying he likes “a style like a cat,” and the two showed an unusual chemistry from their very first meeting—letting their guard down immediately and speaking informally right away. With a warm yet oddly mysterious vibe, the chemistry between “Fox Man” Park Woo-yeol and Min-yoon left even the prediction panel—such as Yoon Jong-shin and Kim Yi-na—stunned, emerging as a major variable for the romance to come.
Kim Kang Yu-gyeong’s tears, “My heart won’t do what I want”
Meanwhile, Kang Yu-gyeong, who had been building rapport with Park Woo-yeol, eventually burst into tears as Min-yoon arrived and Park Woo-yeol’s attitude shifted. Up until that morning, she had been carpooling with Park Woo-yeol warmly and even had a movie date planned—so the sense of loss hit even harder. Kang Yu-gyeong shared her deep anguish over Park Woo-yeol’s ambiguous demeanor: even when he expressed interest, he never seemed to offer certainty.
Kang Yu-gyeong cried as she told her close friend, fellow housemate Kim Min-joo, “I tried hard not to feel anything, but it doesn’t turn out that way.” The timing that got them tangled—she picked Kim Seong-min instead of Park Woo-yeol in the text vote the day before—along with the sight of Park Woo-yeol enjoying a date with Min-yoon pushed her into despair. Even with Kim Min-joo’s comfort and encouragement, Park Woo-yeol’s increasingly chilly attitude weighed heavily on Kang Yu-gyeong’s heart.
Tangled love lines and a preview of a Japanese Tokushima trip
On the day’s broadcast, the complicated emotional currents of other housemates were also shown. Kim Seo-won and Jung Gyu-ri confirmed mutual interest through carpooling and formed a stable flow. On the other hand, Kim Seong-min and Kim Min-joo sparked tight tension as text messages crossed due to a minor misunderstanding. At the end of the broadcast, it was announced that all seven housemates would take a winter trip to Tokushima, Japan, raising viewers’ expectations.
Leading the buzz for romance entertainment in 2026, HeartSignal 5 doesn’t just show simple attraction—it vividly reveals the complex inner worlds behind human relationships and the cruelty of timing. With the arrival of the powerful “Me Ggae Girl,” Choi Min-yoon, attention is focused on what kind of ending the complicated four-sided dynamic between Park Woo-yeol, Kang Yu-gyeong, and Jung Gyu-ri will reach. The next chapter for the young men and women caught in a whirlwind of feelings will air on the 19th at 10:00 p.m.
