Kim Gu Ra has lots of unconditional love for his son Donghyun, better known as MC Gree to some, and it couldn't be more apparent watching the latest recording session of JTBC's 'Old House New House,' on which Donghyun himself guested. 

On the set, Kim Gu Ra admitted, "When I'm not feeling well or going through a rough patch, I turn to my son Donghyun. He's kindhearted and positive so he understands everything. He' always reliable," showing deep affection for his only son. 

Donghyun responded to his father's affections with, "When my dad takes time off work I go on trips with him and also converse with him a lot. I wanted to lend him strength." Seems like Kim Gu Ra has a son he can be proud of!
