KBS 2TV music talk show 'The Seasons - Sung Si-kyung's Eardrum Boyfriend' invited Yoon Jong-shin, Lee Sung-kyung, and Lee Jae-hoon on the broadcast on the 3rd, showcasing classic songs from various generations.

On this day's broadcast, Yoon Jong-shin opened the stage with 'Tired Day' and 'Before Confession,' expressing friendship by presenting a bouquet to Sung Si-kyung to congratulate him on being chosen as MC.

Yoon Jong-shin shared a friendly conversation with Sung Si-kyung, saying, "I'm too robust to be a balladeer who sings the heart of a pathetic man."

Regarding his music career, Yoon Jong-shin said, "I thought of the time when I was passionately creating music as a continent. Now, I think I've become an island somewhat detached." He clarified, "It's not a negative meaning, but it means that Yoon Jong-shin and those who like him gather to sing about a narrower and deeper emotion." He then sang 'Island' passionately, leaving a deep impression on the audience.

Actress Lee Sung-kyung appeared in the 'Two People' corner and shared her feelings about winning the Best Newcomer Award at the 10th Korea Musical Awards for the musical 'Aladdin.' Lee Sung-kyung said, "It was the first time I cried after receiving an award," and mentioned that being a musical actress had been a long-time dream.

Lee Jae-hoon appeared on a music show for the first time in 14 years, performing songs such as 'The Reason I Wanted You' and 'Lucifer's Excuse,' and also showed off b-boying choreography. Lee Jae-hoon said, "I lost weight and styled my hair with a 5:5 parting to show how I looked over 30 years ago," and Sung Si-kyung commented on Lee Jae-hoon's stage manners, calling him "the perfect vocal for popular music." Lee Jae-hoon attracted attention by revealing, "I lost 10 kg in three weeks."

Additionally, Lee Jae-hoon communicated with the audience and spontaneously gifted a song, singing Cool's hit songs such as 'Small Waiting,' 'Melancholy,' and 'Before Trying to Be Sad' consecutively.
