Yoon Jong Shin Disses Sung Si Kyung After 'Ear Boyfriend' Title

Singer-songwriter Yoon Jong-shin humorously expressed his dissatisfaction on his Instagram story after appearing on KBS2's "The Seasons - Sung Si-kyung's Eardrum Boyfriend." He posted a Reels video of the filming with the caption, "Why are they ordering so much lol," and added, "​These guys keep ordering a lot of stuff," drawing attention with his repeated complaints. In the video, Yoon Jong-shin is seen filming with the help of staff to create a three-part split screen, and the phrase "​Eardrum Boyfriend" was written on the video, indirectly referencing the show's MC, Sung Si-kyung. Yoon Jong-shin had previously appeared as a guest on "Sung Si-kyung's Eardrum Boyfriend" on the 3rd.

The episode of KBS 2TV's "The Seasons - Sung Si-kyung's Eardrum Boyfriend" broadcast on April 3rd featured guests Yoon Jong-shin, Lee Sung-kyung, and Lee Jae-hoon. Yoon Jong-shin kicked off the stage by passionately singing "Tired Day" and "Before Confession," and presented the new MC Sung Si-kyung with a bouquet of flowers, showing their friendship. The two reminisced about their musical connection, mentioning songs they had worked on together. Yoon Jong-shin playfully told Sung Si-kyung, "You're too robust to be a ballad singer who sings about the heart of a pathetic man," showcasing their bickering chemistry. Reflecting on his music career, Yoon Jong-shin described it as, "​I thought of that time when I was working hard to create music as a continent. Now, haven't I become a somewhat detached island?" He explained that this was not meant negatively, but rather that he and his fans now sing about narrower and deeper emotions.

Actress Lee Sung-kyung also appeared on the show that day. Lee Sung-kyung recalled winning a rookie award for the musical "Aladdin" and shared, "It was the first time I cried after receiving an award." Lee Sung-kyung, whose dream was to be a musical actress even before becoming an actress, revealed that she had postponed her challenges to prepare perfectly. Lee Sung-kyung showcased her outstanding vocal skills by passionately singing "A Whole New World" and Beyoncé's "Love On Top," and displayed musical synergy with Sung Si-kyung by singing Kim Dong-ryul's "Miracle" together.

Lee Jae-hoon of Cool appeared on music television for the first time in 14 years, performing "The Reason I Wanted It to Be You" and "Lucifer's Excuse," even executing complex B-boying choreography. Lee Jae-hoon drew laughter by saying, "I lost weight and styled my hair 5:5 to show you what I looked like about 30 years ago." Sung Si-kyung marveled at Lee Jae-hoon's stage presence, calling him "​a vocalist who is the answer to popular music." Lee Jae-hoon surprised everyone by revealing, "​I lost 10kg in just 3 weeks" to look like his prime. Lee Jae-hoon also showed his wit by listening to audience members' stories and gifting them songs. When he passionately sang Cool's hit songs, Sung Si-kyung and Lee Sung-kyung made a surprise appearance, creating a stage reminiscent of a concert.

On the show, Lee Jae-hoon stated, "I lost 10kg in 3 weeks." He explained that he was happy when he lost 10kg for last year's concert, which made him look like he did when he debuted, and that for this year's concert, he was told that losing another 10kg would make him look like he did when he retires. Sung Si-kyung responded, "​What's clear is that you seem to lose weight when you're unhappy. I don't think there's such a thing as losing weight happily." Lee Jae-hoon advised, "​You don't look that happy these days either, Sung Si-kyung. Aren't many people happy because you are unhappy?" Lee Jae-hoon admitted the need for management, saying that he used to not even apply skin or lotion but is now "​experiencing the benefits of modern medicine." Sung Si-kyung chimed in, "​If you're a celebrity, you have to manage yourself." Lee Jae-hoon emphasized, "​Having a positive mindset, sleeping a lot. These things absolutely don't work. You need to get management," drawing laughter.
