Hana is cheerful, hardworking, and deeply committed to her job, but she has a peculiar quirk: her inner thoughts often slip out unintentionally, leading to awkward and humorous situations.

The café setting serves as the primary backdrop for the story, with interactions between Hana and her coworkers, customers, and the café owner driving much of the narrative.

The characters are designed to complement Hana’s personality, with each having distinct traits that contribute to the series’ humor and charm.
