Chika runs her family's pet shop with an almost religious devotion to her canine companion, a dog named Rin Tin Tin who follows her everywhere. Their bond goes beyond the usual owner-pet relationship: Rin Tin Tin seems genuinely protective, staying vigilant even while Chika sleeps, as if guardian and guarded exist in some unspoken contract. Life at the shop moves at its own rhythm, filled with the everyday chaos of animals, customers, and the constant comedy that erupts when you mix a girl who loves her dog maybe a little too much with a pet store's endless stream of situations. The humor lands in unexpected places: awkward moments, the absurdity of pet ownership, and the particular kind of warmth that comes from an unconditional relationship between girl and dog. This one-episode OVA captures something genuinely sweet beneath its comedic surface, offering viewers a brief window into a life where the boundaries between human and animal aren't just blurred, they're completely dissolved. It's lighthearted stuff that doesn't take itself seriously, perfect for anyone who's ever felt their pet understood them better than most people do.
