g.o.d.'s Danny Ahn celebrated the group's 13th anniversary today with a special update on Twitter!

On January 13th, Danny Ahn tweeted, "It's g.o.d.'s 13th birthday!!!! Wow~~ kekeke. Congratulations to our members and to everyone who has shown us love all this time! Please carry around a sky blue balloon today. I've put on sky blue earmuffs in celebration haha".

'Sky blue' has been g.o.d.'s official fanclub color since their debut, so Danny Ahn decided to indulge in some fan service by wearing earmuffs in that hue.

Netizens commented, "It's already been 13 years since G.O.D. debuted? Thank you for being with us through all this time", "I won't stop cheering you on. Forever~~" and "Thank you for never changing"

g.o.d. debuted in 1999 as a 5-man group, and gained legendary status over time with their R&B/ballad hits like "To Mother", "Lie", and "One Candle". The members (Yoon Kye Sang, Kim Tae Woo, Son Ho Young, Park Joon Hyung, Danny Ahn) decided to pursue separate careers in 2005, and recently came together for Kim Tae Woo's wedding.
