Jae-ha promotes new self-written single '바보야' mid-10km run on KBS2's 'Salimnam'

Trot running crew, one water incident, one new song

Jae-ha used a 10km televised run to debut her new single 바보야 — literally singing it mid-race on the September 12 episode of KBS2's 살림하는 남자들 시즌2 (Salimnam).

She joined Park Seo-jin, Shin Seung-tae, and Ahn Sung-hoon in what the show billed as Korea's first trot running crew. Park Seo-jin organized the whole thing: team uniforms, a banner, and a 10km course running from a city lake park, across Haneul Bridge, and finishing at a beach. First place would earn a Salimnam studio appearance slot.

The race ran roughly 1 hour and 30 minutes. Shin Seung-tae crossed the line first, Ahn Sung-hoon came second, and Park Seo-jin and Jae-ha followed. Jae-ha finished last, arriving around sunset — but she finished. (Ahn Sung-hoon, for context, had previously abandoned a full marathon course without completing it, so everyone finishing was not a given.)

The low point: Park Seo-jin drank both remaining water bottles at a rest stop before Jae-ha arrived, leaving her nothing. The high point: she kept singing 바보야 anyway.

In a post-run interview with the production team, Jae-ha said "본방사수하겠다" — she'd be watching the broadcast herself.

October half-marathon already locked in

After the run the four moved to a shrimp grill restaurant for dinner. That's when Park Seo-jin revealed he had already registered all four of their names for an October half-marathon. The prize this time: a Salimnam studio appearance plus a solo stage.

Jae-ha's response was immediate: "무조건 하겠다." No hesitation.

바보야, which Jae-ha wrote and composed herself, releases September 15 at noon across online music platforms. 살림하는 남자들 시즌2 airs every Saturday at 10:35 PM on KBS2.
