Kim Su Mi commemorated her wedding anniversary with Dynamic Duo's Gaeko in a sweet Instagram post.

On May 15 KST, the influencer and beauty brand CEO took to her personal Instagram account to share recent photos from the couple's date night, with the final one being of them posing for a selfie in their car.

"Time to celebrate the 11th wedding anniversary with my best friend who has been with me since 24," she wrote. She then used lyrics from late folk singer Kim Kwang Seok's "Around 30" as hashtags – particularly, "What I thought was a lingering youth / Gets further and further away."

In response to the post, her Instagram followers left a number of congratulatory comments wishing the two a happy anniversary.

Meanwhile, Kim Su Mi and Gaeko were married in 2011 and are parents to a son and daughter. The couple commemorated their anniversary with a duet single "Little Treasure," which was released on May 3.
