Lee Jong Hyuk makes a phone call to his wife and his son Junsu on 'I'm Going To School'

Lee Jong Hyuk had an adorable phone call with his wife and son on JTBC's 'I'm Going To School'.

In the broadcast of 'I'm Going To School' on December 6th, Lee Jong Hyuk, Yoon Do Hyun and Nam Joo Hyuk visited Kangnam's house. Later at night, as Lee Jong Hyuk was about to go home, the others asked him to just sleep there together since they would have to go on a picnic with the class tomorrow morning anyway.

Lee Jong Hyuk then made a phone call to his wife to inform about his sleepover, but his wife expressed her frustration and said,"But the kids are waiting for you","They keep asking 'when will appa go home'". His son Junsu suddenly surprised everyone by saying through the phone,"Appa quickly [go home]".

Upon hearing Junsu's voice, Yoon Do Hyun asked,"Do you know who I am?" which resulted in Junsu replying back that he didn't know.
