User is Hwang Hyunjin!

During their concert, Felix was standing up white Minho and Changbin were sitting on the edge of the stage right under him. Hyunjin was sitting on the edge of the stage on the other side, while I.N was standing next to him.

Suddenly, while they were talking, Felix bent down and wrapped an arm around Minho’s shoulders, talking to him as he smiled.

Hyunjin saw this, and he got the smallest bit of jealousy, so when I.N bent down next to him, he rested his head on his shoulder, his legs dangling off the edge of the stage.

Felix saw this after he stood up, his smile faltering as he looked at the two.
