Let's make this birthday one to remember.

40 years old (Born on July 04, 1984)

Happy Birthday, Lee Je-hoon! From your unforgettable portrayal of Ki-tae in "Bleak Night," which earned you a well-deserved Grand Bell Award, to charming audiences as the heart-fluttering architect-in-training in "Architecture 101," you've consistently proven that talent and charisma never go out of style. Whether you're bravely facing battles on screen in "The Front Line" or navigating fashion drama with flair in "Fashion King," your versatility keeps us endlessly entertained.

Here's wishing you another year filled with exciting roles, memorable moments—and perhaps fewer complicated love triangles! Keep dazzling us; after all, age is just a number—but great acting lasts forever.
