Riko is a video game-obsessed office worker in her late twenties whose peaceful existence is disrupted when she adopts a stray cat. Her colleagues are perplexed by her lack of openness regarding her personal life, her absence of overtime work, and her refusal to join them for happy hour. However, Riko is not antisocial at all; she's in a hurry to rush home and play video games. One day, a moggie is discovered in the company's parking lot, and before Riko knows it, it has moved in with her! Riko, who is inexperienced with domesticated creatures, employs lessons picked up from games to teach herself about feline care. Meanwhile, her adorable companion tries to comprehend her habits by seeing things from a feline's perspective.
