Gallavich AU – The Fault in Our Stars Ian Gallagher is your average sarcastic teenager, well, plus a set of lungs that don't work and a body that had once been savaged by cancer. Now he's just living with it. The whole thing is a droll monotonous ride, passing by in immeasurable amounts of time, that is until he meets the rough-around-the-edges Mickey Milkovich at Cancer Kid Support Group. Mickey is unlike anyone else Ian has met, and he gets what it means to be a teenager with cancer living in the South Side. They strike up a friendship of sorts and Ian thinks that maybe Mickey is going to be the great star-crossed love of his life, but does Mickey have other ideas? Does fate? Find out when Shameless meets The Fault in Our Stars.
