A guy trapped as a dog gets to experience his unrequited crush's genuine affection every single day, even though she has no idea who he really is. The premise sounds like a setup for wish fulfillment fantasy, but the show is actually about the loneliness of being close to someone while being completely unknown. It's asking: if you could be loved by your crush unconditionally, but never tell her why you're there, would the love even count.
A college student wakes up with four legs and fur. Somehow, impossibly, he's become a dog. The worst part? The best part? The girl he's hopelessly crushed on for months, Inukai-san, finds him on the street and takes him home. She loves her new pet absolutely, showering him with affection and care he never dreamed possible as a human. He desperately wants to return to his original form, but each day he spends curled up in her lap, hearing her call him a good boy, makes that goal feel less urgent. There's a strange comfort in being wanted this badly, even if she doesn't know it's really him. His canine perspective shifts everything. Everyday moments become precious. A simple pat on the head feels like validation. But living this double life creates constant tension: the desire to confess everything wars against the fear of losing the closeness he's finally found. As weeks pass, he must confront whether returning to humanity is worth sacrificing the unconditional love he's discovered.
