Oh Sang-cheol, 47, works himself to death at his desk in Seoul — and wakes up as a dachshund puppy in a pet shop. Adopted by Kim Ha-rin, a 19-year-old livestreamer who names him Gimbap, the former salaryman discovers his ballroom dancing and "acting" make them both internet-famous. A comedy slice-of-life about fame, family, a cold war with Ha-rin's boyfriend — and one very good second life.
