Yang Se-chan Hints He Knows Lee Ju-yeon's Ex on 'Running Man'

Yang Se-chan dropped a pointed hint on Running Man that he knows who actress Lee Ju-yeon previously dated, setting off a brief standoff on the Aug. 16 SBS broadcast.

Lee Ju-yeon, a former After School member, returned to the show for the first time in eight years alongside guests Jung Eun-ji and Kim Ji-eun for a summer race segment called 무더위엔 긁캉스 (Summer Heat Scratch Vacation). During the episode she opened up about her love life, saying she has not been in a relationship and that "from a year ago I started wanting to be in love." She added, "I want to meet a good man soon."

Then she asked Yang Se-chan directly whether he was an "idol killer." His response came fast: "I also know the person you met. Should I tell? Let's see who has a bigger impact. I won't stay quiet anymore." Lee Ju-yeon shut it down immediately. "Let's both stay quiet."

The moment carried weight. Lee Ju-yeon has been linked to Big Bang's G-Dragon in multiple dating rumors over the years, though neither side ever officially confirmed anything. Yang Se-chan never named anyone, and the show moved on.
