Super Junior's member Donghae revealed his handwritten letter in celebration of 9th anniversary with their fan club.

"ELF, happy 9th birthday. I like writing letters so I wrote one for you. Please keep supporting us. Don't be sick, eat well, and smile a lot. I love you," posted Donghae on his Instagram on Tuesday along with a picture.

In the picture, the letter reads, "ELF, happy 9th birthday! It's already been 9 years since we started walking together. A lot of things happened, right? We laughed together, cried together, and helped each other out when we were going through hard times. ELF is really something Super Junior cannot live without."

It continued, "I was happy to meet you when we first met, thankful to get close to you, and happy to be able to love you and we have so many great memories together. I hope we can love each other as if there's no tomorrow. I love you."
