Haha, Kim Jang-hoon, Kim Jong-kook & Jung Eun-ji line up for The Seasons – Sung Si-kyung's Ear Boyfriend

KBS 2TV's 더 시즌즈-성시경의 고막남친 (The Seasons – Sung Si-kyung's Ear Boyfriend) aired August 14 at 11:30 PM with Haha, Kim Jang-hoon, Kim Jong-kook, and Jung Eun-ji as guests.

Haha performed his recent remake of 노래만 불렀지 with the song's original artist, Kim Jang-hoon. During the stage, KBS deployed KAIROS—the broadcaster's self-developed AI portal system—to pull up archival footage of both performers in real time. Haha also opened up about 무한도전's 20th anniversary: "I hated being mediocre among geniuses."

Kim Jang-hoon has logged roughly 3,500 concerts across his career. He pushed host Sung Si-kyung into a duet on 세상이 그대를 속일지라도, saying he wanted "to draw out Sung Si-kyung's shouting." He also ran through a hit-song medley spanning ballads to uptempo tracks.

Kim Jong-kook returned to the show for the first time in about three months. He's currently in the middle of a 30th-debut-anniversary project in which artists with distinct musical identities write songs for him to reinterpret in his own voice. On the episode he performed Melomance's 사랑인가 봐 live.

Jung Eun-ji came back with a solo album after five years. She took the duet corner 두 사람 and performed All For You with Sung Si-kyung. She revealed she warms up her voice in the waiting room with Woo's Drowning. (Vocal warm-up lore is always welcome.) On her new album she described her approach to love as: "I am the pursuing type" and "I fearlessly keep charging."
