Lee Seung Gi, why did you collaborate with Cha EUN WOO (ASTRO)? ”20 years ago, there were a lot of older sister fans...”

Singer and actor Lee Seung Gi revealed the reason why he decided to do a duet with Cha EUN WOO (ASTRO).
Lee Seung Gi appeared as a guest on FM4U's "Noon Hope Song Kim Shin Young."
On this day, Lee Seung Gi said, "Even just listening to the intro of 'You're my girl' makes me sad. It reminds me of the hardships I went through," and added, "I empathize with the song and feel excited when I sing it."
However, she made everyone laugh by saying, "No matter how I sing "You're my girl" anymore, people won't be interested in it."
She continued, "In 2004, I was in my teens and had a lot of older sisters, but now there are fewer of them. So, I'm just a close younger brother and junior.
Lee Seung Gi released his album "With" at 6pm on the same day to celebrate his 20th debut anniversary.
EUN WOO participated as a featured artist in "You're my girl."
