Eun-mi is just like any other woman her age, with the exception that she gave birth to her daughter, Jin-hee, while she was in high school. Living under the same roof as Eun-mi is no different for Jin-hee than raising her own daughter, and it's often difficult to determine who plays the role of the mother. Despite their roommate-like conflicts, deep down they know they can rely on each other when things get a little too chaotic. As a fresh day begins, Eun-mi and Jin-hee step into another day of their remarkable journey, where the ordinary becomes extraordinary in their uniquely intertwined lives.
