Apink, a representative "long-lived girl group" in the music industry, will release a song to fans on the 19th to mark the 10th anniversary of their debut.

The agency PlayM Entertainment announced that Apink will release its 10th anniversary special digital single "Thank you" on major music sites at 6 p.m. that day.

"Thank You" is Apink's "Fan Song," which marks the 10th anniversary of its debut on this day, with a message for fans who have been with it for 10 years. It is also the first new song in more than a year since its ninth mini album "LOOK" released last year.

Bomi Yoon, a member of the group, participated in the lyrics and expressed her sincerity, and Double Sidekick, a producer with special ties to Apink, such as "Mr. Chu" and "Starry Star," presented songs to celebrate the 10th anniversary.

The music video for "Thank You" also contained Apink's preparation for the exhibition with memories with fans.

Starting with online exhibitions and pop-up store "Pink Carnival" last month, Apink started its 10th anniversary event.

Apink, which debuted with "MOLAYO" in 2011, has created several mega-hit songs such as "Mr. Chu", "LUV", and "NoNoNo". The recently released "I'm So Sick" and "Dumhdurum" have also shown successful concept changes, building meaningful moves as active girl groups that have been running for 10 years.

Each member has also achieved achievements in various fields, including solo albums, acting, entertainment, and advertising.
