Inu to Owamari-san

A former police officer named Wang Ming-hao opens a pet shop to honor his deceased friend's wish, but struggles to attract customers due to his imposing presence. After taking a nap, he wakes up transformed into a dog. A boy then appears, revealed to be a former stray taken in by his late friend. As unusual occurrences continue, Wang seeks assistance from Li Taiyang, a part-time job applicant, in hopes of finding a way to revert to his human form.
