Sung Dong Il asked his son's fans to refrain from expressing their love perhaps a little too roughly during the excitement of seeing him out on the streets.According to an article in Soompi, his 7-year-old son Joon has been receiving an incredible amount of love because of his adorable yet mature image for a child on MBC's 'Dad! Where Are You Going?', but the excessive love has Sung Dong Il worried a little.On SBS' 'One Night of TV Entertainment', the actor said, "Thanks to Joon, our family is doing well. I'm thankful. But I wish people would love him up to a certain boundary. There are many people who show their love a little excessively by yanking on the back of his neck [to get a look at him]."
