When Tir comes home from a ten-day job, he's not expecting to find a mechanic's kit where his flight bag goes, an altitude jacket where he'd normally keep his flight vest, and his girlfriend Eiren sitting on the lap of some guy he doesn't know.
But Eiren says that she expects Tir to do whatever he can to make her friend happy, so Tir's going to give it his best shot . . .
