Synopsis

About Maru is a Puppy

Woo-Ri’s 5-year old poodle mix, Maru, has turned into a human — a 5-year old little girl, that is! Now Woo-Ri’s gone from pet owner to big sister, and it’s her job to keep Maru out of trouble. Human Maru has the same endless curiosity and playfulness of a puppy, but now she can walk into grocery stores, go to kindergarten, and check this out — hold things with her opposable thumbs. Being human rules! (Source: WEBTOON, edited)
