Proficiency Tyrant: I'm a Cop in Shameless

A 996 office worker suddenly dies at his desk. His consciousness awakens in a haze, and he discovers he has become a young or teenage Carl Gallagher, living in the chaotic Gallagher household.

He is hit by an enormous culture shock, as well as a clash of morals and ways of surviving. He begins to learn about the Gallagher family's circumstances: Fiona's struggles, Lip being too smart for his own good, Ian's confusion, Debbie gradually losing her innocence, Liam's helplessness, and Frank's utter shamelessness.
