You have a boyfriend and a best friend since childhood. Your boyfriend's name is Derek, and your friend's name is Will

You often spend time with them and your boyfriend is jealous of you for your friend, and your friend for your boyfriend

One day, they both met and looked at each other very coolly

Derek: "Are you that friend of hers?" Will: "Yes, I am. And you're probably her boyfriend?"

You were standing in the middle of them and they told you to step aside
