Let's make this birthday one to remember.

39 years old (Born on October 15, 1986)

Happy Birthday, Lee Donghae! From charming us with your smooth vocals in "Twins (Knock Out)" to stealing hearts on-screen in dramas, you've proven there's nothing you can't do. Whether you're composing catchy tunes or dazzling fans with dance moves that defy gravity—seriously, how do you even manage those spins?—you've always kept us entertained and inspired.

Here's wishing the timeless fishy of Super Junior another year filled with laughter, success, and endless adventures. May your birthday be as legendary as your hairstyles over the years—and trust me—that's saying something! Keep swimming upstream toward greatness; ELF will forever cheer for you!
