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. Maru retains her energetic and curious nature, now able to explore the world in new ways, such as entering stores, attending school, and using her hands to interact with objects. Woo-Ri must ensure Maru stays out of trouble while adapting to her new human form.
