Can you believe they are still in elementary school?

Long-time fans will remember the show The Return Of Superman, which introduced one of the most well-loved Song triplets, Daehan, Minguk, and Manse, the sons of actor Song Il Kook.

Many fans have watched the show since it aired in 2013 and have watched the triplets grow up together.

Even just a few months ago, a video of the triplets went viral online, garnering over one million views in less than 24 hours.

Most recently, the triplets went viral once again, showing even more growth than before, as they made an appearance on tvN‘s You Quiz On The Block‘s official Instagram.

“Along with the original superman ‘Song Daddy’ Song Il Kook, and the entire nation’s online nephews that gave healing to aunts and uncles all over the world, Daehan, Minguk, and Manse, have come to You Quiz!'

They have already grown so tall that they have surpassed Jo Seho’s height. Are you curious about the triplet’s huge growth? Take a look on You Quiz!”
