Seventeen made their official debut on May 26, 2015. To commemorate the special date, the members shared hand-drawn images that held a special message for their fans! With thirteen Korean characters, each member decorated a letter with simple aesthetics or creative designs. The end result of the sentence spelled out, "Thank you, Carats who have been with us for 3 years."

In the corner of every drawing, you can find the name of the member who drew it. Congratulations to Seventeen on their 3rd anniversary!
