Channel A’s dating reality show Heart Signal 5 has been rocked by a major shake-up after new contestants moved in. A nail-biting love triangle involving the men competing for one woman unfolds in earnest, drawing viewers’ intense attention.
The production team of Heart Signal 5公開了 the moment when eight housemates (Park Woo-yeol, Kim Seong-min, Kim Seo-won, Jeong Jun-hyeon, Kim Min-ju, Jeong Gyu-ri, Kang Yookyung, and Choi So-yoon) set off for their first overseas trip to Japan’s Tokushima. In an unfamiliar environment far removed from everyday life, the emotions of these young adults escalated and intersected even more sharply.
After finishing their meal at a local ramen shop in Tokushima, they dove into conversations aimed at matching for real dates. Jeong Gyu-ri kicked off the tension’s opening act by suggesting a way for the men to pick their date first and then deliver the notification.
In response, the male contestants revealed their hidden “straight-for-it” instincts. Kim Seo-won, without hesitation, expressed that he wants to spend their first evening together in Tokushima with Kim Min-ju.
The advances from three men toward Kang Yookyung…A sharp clash between Jeong Jun-hyeon and Park Woo-yeol
The peak of the conflict came from the choice involving Kang Yookyung. When dermatologist Kim Seong-min pointed to Kang Yookyung, even Jeong Jun-hyeon—the “catfish man” who joined the house—also made it clear that he wants to spend time with her, baring his bold inner feelings.
When provoked by Jeong Jun-hyeon, Park Woo-yeol—who had been forming a rosy mood with Kang Yookyung all along—immediately fired back. Park Woo-yeol said he wouldn’t back down, insisting that if things unfolded like this, he would choose Kang Yookyung no matter what.
In an instant, a once-in-a-lifetime situation erupted where three men confronted each other over a single woman. The sharp exchange of glances between Jeong Jun-hyeon and Park Woo-yeol even made the studio prediction panel tense. As the emotional divide deepened, Kim Seong-min stepped in by proposing “Men’s Talk,” a conversation among the men only, temporarily sealing the tense nerves.
