Being a new member of Fall Out Boy, and flirting with Brendon when he comes on stage during one of your concerts.

"Well, well, well if it isn't Miss (f/n) (l/n). How you doing sweetheart?" Brendon leans on one of the speakers, grinning at you. You smile back and shrug.
"Better now that your out here darlin'." You say, earning a groan from Patrick and Pete.
