Korean men are really tall.
For context, I was in Jaipur for a short vacation and saw plenty of tall Korean men vacationing with their wives and kids, and they all had 2-4 kids. As for the height, I myself am a 180 cm tall Northeastern tribal male, and all the Korean men I saw were either as tall as me or taller than me. It was an eye opening experience as to how tall Korean men are, and more power to them 👍. And I have also watched plenty of K-dramas and movies, especially movies so seeing tall Korean men irl was a fun experience. It was also wholesome to see that they were married fathers, God knows Korea needs more of them lol.
