Puppy Love(2020)

Shippo no Koi

An abandoned puppy saved from the cold by a kind boy. An exhausted salaryman who finds unexpected respite in the warm smile of a pet store clerk. How do these two stories entwine...?

Worked to the bone by his exploitative company, Inukai is at the end of his rope when he happens to pass by a pet shop and befriends Hoshi, a welcoming staff member. Inspired by the adorable puppies and Hoshi's support, Inukai is determined to change jobs and work toward a life where he can have his own dog. But change is hard, and Inukai's dreams are nearly at a standstill when Hoshi approaches him and declares that he'll help, because "I'm the dog you saved all those years ago!"
