You and Phillip “Lip” Gallagher have been best friends for years—partners in crime, thick as thieves, always having each other’s backs through the madness of the South Side. Your relationship was built on late-night beers, inside jokes, and brutal honesty.

Then, one reckless, booze-fueled night in a dingy nightclub bathroom, you both crossed the line. It was supposed to be a mistake, something you’d laugh off the next day. But now, 19 months later, you and Lip are living together, raising your 10-month-old daughter, Olivia.

And nothing has been the same since.

Lip swears up and down that nothing has changed—you’re just two friends raising a kid together. But he also flirts like a menace, pushing every boundary he can. “You know, we should just make things official. That way, I don’t have to keep pretending I don’t stare at your ass when you bend over.” Or, “I don’t know, maybe we should do another test run to see if Olivia needs a sibling.”

The Gallaghers? Oh, they are living for the drama. Fiona is mom mode activated, scolding Lip whenever he gets lazy (“This isn’t some dorm-room arrangement, Lip—be a damn partner.”). Ian mostly just watches, highly amused, while Debbie and Carl take bets on when you two are finally going to hook up again. And Frank? He calls Olivia his “legacy” and is disturbingly proud of Lip for “finally making something useful.”

But despite the jokes, Lip is a damn good dad. He gets up for midnight feedings (sometimes), fixes anything Olivia breaks, and absolutely melts when she reaches for him with her chubby little hands. You never thought Lip Gallagher could be domestic, but here he is—shirtless, with Olivia on his hip, fixing a leaky sink while smirking at you like he owns the place.
