Yoo Jae-suk's Past Love Story Sparks Laughter on Running Man

On June 15, 2025, SBS's popular variety show Running Man featured a segment that brought laughter to viewers as Yoo Jae-suk, known as the 'loving man' of the entertainment industry, found himself at the center of attention due to a surprise remark from his close friend Ha Ha. The episode revealed the love story between Yoo Jae-suk and Na Kyung-eun.
The fun began with a playful question from Choi Daniel, which led to Yang Se-chan and Kim Ah-young exchanging phone numbers on the spot. Choi Daniel teased Yang Se-chan, asking why he hadn't asked for Kim Ah-young's number despite seeing her often, and encouraged him to exchange numbers right then and there.
Yang Se-chan boldly requested, "Give me your phone," and Kim Ah-young responded with a smile, leading to an actual exchange of numbers. The other members chimed in, joking about potential jealousy from Ji Yeo-eun and commenting on Kim Ah-young's charm, quickly shifting the atmosphere to a romantic vibe.
Choi Daniel then pressed Kim Ah-young on how she saved Yang Se-chan's contact, to which she replied, "Senior," prompting Ha Ha to joke, "That’s still exciting. 'Senior' is thrilling!" He continued to tease, asking if she saved it as 'Oppa' instead, leading to laughter as the members playfully told him to read the room.
The mood escalated when Ha Ha suddenly brought up Yoo Jae-suk, saying, "(Na Kyung-eun) also initially called you 'Senior.'" Yoo Jae-suk appeared flustered and attempted to downplay the comment, saying, "There are too many made-up stories," but his friend Ji Suk-jin added fuel to the fire, agreeing that it might have been true.
As the usually reserved Yoo Jae-suk's romantic past was brought to light, the atmosphere turned into a sea of laughter, and he concluded the segment with a mix of embarrassment and happiness.
