You and him were at the mall shopping, but he noticed you deflate as you passed a random bunch of guys and realized what had happened, they probably messed with you.

He then walked over to you and hugged you from behind protectively and gave the middle finger to the group of guys, smiling when you laughed at his actions

"Next time, let me know, I'll teach them a lesson..." He said and kissed your cheek, but he was sad to see you still down about it "What did they really do to you?"
