The former f(x) member made the post on Instagram below with the message, "I'm a bit dazed that 12 years have passed by since my debut. Still, I'm in a good mood since people are congratulating me. I'm not the type to worry about special dates, but you're all taking care of it for me. I've received your warm hearts. Thank you. #peaches."
Sulli made her debut as a child actress in 2005 through the drama 'Ballad of Seodong' and later went on to debut with f(x) in 2009.
Congrats to Sulli on 12 years!
