Yang Se Chan has found himself at the center of fresh relationship speculation after a Running Man segment spiraled into one of the episode’s most talked-about moments. What began as a variety-show game built around awkward, provocative questions quickly turned into a near-confession on air, and viewers wasted no time treating it like a real reveal. According to Koreaboo’s recap and Korean entertainment coverage, the setup came during a mission designed to make cast members uncomfortable: if the person being questioned answered “yes,” points were awarded, while refusing to respond brought a penalty. That format created the perfect opening for Yoo Jae Suk to throw a loaded question directly at Yang Se Chan.
Yoo Jae Suk reportedly did not ease into it gently. Koreaboo says he first teased Yang Se Chan by saying he would not go so far as to name the group, then asked the question that immediately sent the set into chaos: had he ever dated a girl group member before? The way the question was framed is important, because it turned what could have been dismissed as a vague joke into something much more pointed. By signaling that he supposedly knew enough to avoid naming names, Yoo made the moment feel less like random teasing and more like a deliberate attempt to expose a real part of Yang Se Chan’s past.
What pushed the clip into viral territory was Yang Se Chan’s response. According to Maeil Business/Star Today’s English report, when asked whether he had dated a girl group member, Yang replied, “Yes,” after reacting with visible discomfort and asking why Yoo Jae Suk was behaving that way. The same report adds that Kim Jong Kook immediately pounced on Yang’s hesitation, joking that the pause before the answer made it sound even more real, and saying the others already knew it was true. That combination — a direct question, a “yes” answer, and instant cast reaction — is why so many viewers came away feeling they had just witnessed a genuine admission rather than a throwaway gag.
Koreaboo framed the scene even more directly, describing the moment as Yang Se Chan “admitting” he had dated a girl group member. Its recap emphasizes that viewers latched onto his reaction because he did not deny the claim in a clean or obvious way. Instead, his answer appeared to confirm it enough for online audiences to start revisiting older rumors and speculation about who the idol might have been.
At the same time, the reporting also makes clear that this was still delivered within the language and structure of a variety show. The exchange happened during a game specifically designed to provoke revealing or embarrassing answers, and no outlet in the available coverage identifies the alleged former girlfriend by name. In other words, the moment may have sounded like a confession, but it was still packaged as entertainment, not as a formal statement from Yang Se Chan about his private life. That distinction matters, especially in K-entertainment, where playful on-air banter often fuels rumors far beyond what was explicitly said.
The buzz did not stop there. The same Maeil report says Yang Se Chan was later asked if he currently has a girlfriend, and he answered “Yes” again. That detail added another layer of intrigue to the segment, because it suggested the show had moved beyond discussing an old idol relationship and into his present dating life. In a single broadcast, Yang was effectively portrayed as confirming both a past romance with a girl group member and a current relationship, which helps explain why the episode immediately became gossip fuel.
Other coverage around the episode shows just how much relationship chatter was already surrounding the program. Chosun and Biz Chosun also highlighted dating-rumor discussion tied to the same broadcast, including separate attention on Ji Ye Eun and the show’s teasing treatment of romance-related storylines. That wider atmosphere likely made Yang Se Chan’s remarks land even harder, because the episode was already primed for viewers to read flirtation, jealousy, and past dating history as major talking points.
What makes the moment so effective as television is also what makes it so slippery as news. On one hand, Yang Se Chan seems to have given a direct enough answer that multiple outlets treated it as confirmation. On the other hand, the setting was engineered for maximum chaos, and the entire cast clearly understood how explosive the question would sound. The laughter, the pressure, and the follow-up commentary all helped turn a single response into a mini-scandal.
So the bigger takeaway is not that the mystery has been solved. It has not. No name was given, and no detailed timeline or identity was confirmed in the available reporting. What the episode did provide was something almost more potent in celebrity culture: just enough apparent truth to make fans, viewers, and gossip outlets run wild. In the world of variety TV, that is often all it takes. And for Yang Se Chan, one brief “yes” was enough to set off an entirely new round of speculation.
