Kang Yoo-kyung's expression after seeing Choi So-yoon and Park Woo-yeol's couple ring on 'Heart Signal 5.'

On Channel A's 'Heart Signal 5,' which aired on May 26, Choi So-yoon raised the tension by wearing a ring with the same design as Park Woo-yeol's. The eight residents traveled to Tokushima, Japan, where they enjoyed one-on-one dates.

Choi So-yoon and Park Woo-yeol, who took a train trip to the outskirts, bought matching couple rings at a gift shop, wore them together, and enjoyed a date at a dyeing workshop. Choi So-yoon openly expressed her feelings, saying, "I like the innocence of someone younger." After the date ended, when everyone gathered and Choi So-yoon fiddled with the ring she was wearing as a couple item with Park Woo-yeol, Jung Joon-hyun was surprised and said, "You two are wearing the same ring?" Kang Yoo-kyung's expression then stiffened.

Kim Min-joo showed interest in Kim Sung-min, and Kim Sung-min made her smile by saying, "I think there are about two people I am interested in. Kim Min-joo is included." Kang Yoo-kyung and Jung Joon-hyun grew closer as they began speaking casually to each other. Jung Joon-hyun confessed his sincerity, saying, "I think my eyes are drawn to you the most." Jung Gyu-ri and Kim Seo-won enjoyed a date in the forest, where Kim Seo-won appealed to her by saying, "I think today will be the most memorable."

That day, for the first time, all four couples succeeded in exchanging text messages with their date partners, allowing the celebrity prediction panel to enjoy the satisfaction of getting their deductions right. At the end of the episode, a preview also showed Kang Yoo-kyung, who had returned to Signal House, appearing to suggest a movie theater date to Park Woo-yeol.

'Heart Signal' is a program that observes the romances of young men and women unfolding in Signal House and asks viewers to infer the final couples.
