A little otter who finds nothing more amusing than telling lies is the heart of this story. The protagonist describes herself as adorable but not very wise, taking great joy in mischief and deception. She smiles, laughs, gets angry, and cries, but most of the time, she is simply pretending. For her, lying is a delightful game.

The manga is a slice-of-life seinen following the daily antics of this cute but dishonest otter as she navigates a world filled with other animals. Her lies range from small, harmless fibs to more elaborate acts of pretend, all presented as playful rather than malicious. The setting appears to be a gentle, everyday environment where her constant stream of untruths creates humorous and heartwarming situations. The artwork is notable for being presented in full color, enhancing the lighthearted and charming tone of the story.

The narrative arc focuses on the otter's various exploits and the reactions of those around her. Each chapter or episode likely presents a new situation where her love for deception leads to a series of amusing consequences. The core conflict is not external but internal to her personality: her compulsive need to lie versus the simple, honest world she inhabits. The story explores the boundaries between mischief and harm, as her lies, while cute, have the potential to affect others. The manga celebrates the playful and slightly naughty side of a young animal who finds the world to be her stage for an endless performance.
