Kim Da-mi takes on the role of Jo Yi-seo, a brilliant high school student turned manager of a pub named DanBam. Energetic, stubborn, and astute, she has a bratty and impulsive side to her while also radiating an unmatched self-confidence. A social media expert with a quick grasp of what’s hot and trendy, she transforms a struggling bar in the posh area of Itaewon into a flourishing restaurant in the food and beverage industry across the world. Despite her remarkable talent, she is far from perfect. Her sociopathic tendencies, mixed with moments of insensitivity and obnoxiousness, make her unpopular. However, as the show progresses, she gets the character growth she really needed, evolving into a compassionate and collaborative team player.
