The manga follows a main character who steps into a "second life" with a self-imposed challenge: never touch a single drop of alcohol. Despite this strict restriction, the protagonist frequents authentic bar settings, stepping into the beautiful, deep world of mocktails (non-alcoholic cocktails). The story beautifully showcases how expert bartenders create sophisticated, complex drinks that rival real liquor in both flavor and presentation. Beyond the gourmet elements, it is a heartwarming slice-of-life drama that proves you can still enjoy the mature, comforting ambiance of a night bar and connect with others without needing alcohol.
