Jaehyun :
As soon as he saw this guy walking up to you he knew he was bad news. Jaehyun wouldn't care to be polite to him. He'd make it a point to not show any emotion other than annoyed and upset. Jaehyun wouldn't be straight forward with the guy but he'd try to get him away from you.
Doyoung :
Doyoung would be upset about the situation. Would give the guy a dirty look while he wrapped his arm around you. He'd try not to cause any trouble but he didn't like seeing someone being so "friendly" with you. Especially when he was standing right there.
Johnny :
He's more protective than possessive. Would be concerned about you being uncomfortable in this situation. He wouldn't play the boyfriend card unless the guy had tried to pull anything way too inappropriate on you. The guys actions would disgust him and he'd feel sorry that you have to go through that.
