On the February 10 broadcast of KBS2's 'Superman Is Back', Ko Ji Yong and his son Seungjae visited the home of Ko Ji Yong's close friend - actor Shim Ji Ho!

On this broadcast, actor Shim Ji Ho confessed that he married privately back in 2014, and many people still have no idea that he's married with two kids. The actor debuted as a hi-teen star through KBS2's 'School 2' in 2000. 

Shim Ji Ho then introduced viewers to his adorable two children: 6-year old son Ian, and 15-month old daughter Ielle!

Same age friends Seungjae and Ian hit it off immediately from the start, as the outgoing Seungjae introduced himself first, and the two boys quickly became immersed in talking about dinosaurs! Check out some fun clips from this week's 'Superman Is Back' below, featuring Seungjae and Ian's friendly handshake, to Ian witnessing his dad's drama kiss scene with confusion, etc!
