An So-hee, Han Ji-yeon, and Kang Ji-gu are heavy drinkers who became best friends by drinking together. So-hee is a broadcast writer. She has a bad drinking habit, but is professional at work. Ji-yeon is a yoga instructor with a lovely image, but can be tactless at times. Ji-gu is a YouTuber who spends most of her time cooped up in her room. Joining the trio is the eccentric yet humorous variety show producer, Kang Buk-gu.
