Maru-neun Gangjwi

A five-year-old poodle mix named Maru transforms into a human child, also five years old. Her owner, Woo-Ri, becomes her big sister and takes on the responsibility of watching over her. As a human, Maru retains her energetic and curious nature but now has new abilities, such as using her hands to grasp objects and participating in activities like attending school and shopping. Adjusting to her new form, Maru explores the world with the same enthusiasm she once had as a dog.
