Let's make this birthday one to remember.

48 years old (Born on February 28, 1977)

Happy Birthday, Jo Sung Mo! From your debut with the tear-jerking ballad "To Heaven," you've been making us cry—and we love you for it. Who knew sadness could sell millions? Clearly, tissues owe their booming sales to your soulful voice.

Through countless hits and timeless melodies, you've proven that ballads never go out of style. Your music remains as fresh today as when you first melted hearts back in 1998. Here's wishing another year filled with success—may your songs continue topping charts and breaking hearts (in a good way). Keep singing; we'll keep sobbing happily along!
