Maybe it might not be really hitting.
But there isn't a need to push him on his chest. Should have just call him or say nicely. No need to use hand. They are Idols.

Even if it's friend, there still a limit. Looking at TaeTae is already Moving but still push?

I'm really sad about the one that happen to Kookie ㅠㅠ How scared must he be feeling :( The Manager aren't the same one.
