You and Zack were in terrible traffic, the cars and even the motorcycles were barely moving. A guy who was driving a car just behind you rolls down the window and starts flirting with you. Zack listens and takes off his helmet

"Who do you think you're talking to? She's my fucking girlfriend!" he said in an angry tone, he looked at you to see if you were okay and then at the guy, he's quite jealous and possessive so you can already imagine what's going to happen...
