So, Basically, Stray kids were at a concert, doing silly stuff/dancing/singing/playing around, mostly doing whatever they were doing.

Lee know and han have been very close lately, Lee know smacking han's ass..

So at this concert, Han noticed a fan staring at his arm, admiring how Han's arm looked, and Lee know got jealous, so han quickly covered up and Lee know nodded, fixing the jacket han has used to cover himself
