Jung Hae-in, pumping up his forearms while making Dujonku… Are you watching Go Yoon-jung?

Jung Hae-in appeared on Secret Santa Club
I made a dojo for Go Yoon-jung haha

I also shell the pistachios myself.
They even showed their sincerity by saying that it is expensive because it requires a lot of work.

Are you looking at Go Yoon-jung while pumping her forearm muscles?
The scene that made fans laugh was really cute and heartwarming~~
