Let's make this birthday one to remember.

38 years old (Born on October 06, 1986)

Happy Birthday, Ah In Yoo! Another year older and still effortlessly stealing scenes—seriously, how do you manage to make every role unforgettable? From your captivating performance in "Burning" that left us all questioning reality, to the intense charisma of "Hellbound," you've proven time and again you're not just an actor; you're a mood.

Here's wishing you another fantastic trip around the sun filled with more iconic roles (and fewer apocalyptic cults). May your birthday be as timelessly cool as your style—and may Netflix never stop recommending shows starring YOU. Cheers to many more years of brilliance ahead!
