Brian and Hwanhee shared, "Hello, it's Fly to the Sky! Fly to the Sky have finally reached our 15th anniversary. We've been through a lot up until now. We also did solo promotions. It feels like we made our debut just the other day although it was 15 years ago. Time definitely flies. I still remember Hwanhee's ramen hairstyle. We reunited as Fly to the Sky after 5 years, and we thank you for giving us the honor to be #1. We're also having a fan meeting today. We're having a concert with Gummy at the end of the year as well, and we will continue to find you and perform, so we hope that you don't get disappointed. We're always thankful, and always be healthy. We hope to see you for a long, long, long time. Thank you."

Happy 15th anniversary to Fly to the Sky and their fans!
