Kim Jong Kook was spotted hanging out with his mom at an arcade recently.

Photos of the mother and son enjoying a friendly game together surfaced online on the 9th. Fans are commenting that it's another side to the singer, who's known for his masculine, 'Sparta' character on 'Running Man' as well as other variety programs.

Agency JK Entertainment commented, "When he has no programs in his schedule or if he goes on vacation, he usually takes his mother with him. On this day, it seems like he went to the arcade with his mom to reminisce over his childhood days and create more fond memories."

Kim Jong Kook recently made a comeback with "Men Are All Like That" from his 7th full-length album 'Journey Home'.
