Park Jin Young, Young K, Jorji & Lee Sang-jun line up for The Seasons – Sung Si-kyung's Ear Boyfriend

Park Jin Young takes The Seasons – Sung Si-kyung's Ear Boyfriend on July 31 at 11 PM. Lee Sang-jun, Jorji, and DAY6's Young K join him.

Park Jin Young opens with a medley: 날 떠나지마, 그녀는 예뻤다, When We Disco. He closes with WET and an encore. KBS pulls archive footage of his past music-show stages and outfits via KAIROS, their AI portal system. He and host Sung Si-kyung swap signature songs for a special stage. Sung Si-kyung practiced at the JYP building the day before filming. Park Jin Young said it was "the first time teaching someone directly since ITZY."

Comedian Lee Sang-jun is the show's first comedian guest. The KBS studio space was once the waiting room for comedian auditions. "I failed here about eight times," he recalled. His next goal is a Gocheok Sky Dome concert.

Jorji performs 바라봐줘요 as a duet with Sung Si-kyung. His stage name nearly became 이죠지, he revealed in behind-the-scenes footage. "I got to hear the intro I had imagined in reality," he said.

Young K just released the 15-track album YOUNGEST. He discusses 작업실에서 커피를, a collaboration with Seon Woo Jung-ah. "We met in the recording studio and talked about the song on the spot, and the guide vocal completed that day was released as the official track — it was like the movie Begin Again," he said.

The show ranked first in weekly topicality among KBS non-drama programs in Q2 2026, per GoodData Corporation's TV-OTT topicality survey.
