Stress is no stranger to the members of Marketing Team 3 of the home appliance department at the Gaus Electronics HQ. The firm is a busy, multinational company, but this is a team that most workers dream of getting out of - and where chaos is no stranger. Some 10 employees make up the team. These include Lee Sang Sik, a man with an upbeat personality who often misjudges his coworkers' moods, causing trouble as a result. There is also Cha Na Rae, the hot-tempered assistant manager. Also among their number is Baek Ma Tan, the heir of the owners of Gaus Electronics' fiercest rival - Power Group. He was born with a silver spoon in his mouth and has never known hardship. But he shocked his entire family when he decided to join Gaus as a junior employee. His polar opposite is Geon Gang Mi, who comes from more modest origins and has always tried to pull herself up by her bootstraps - pushing herself to succeed at every step. While they seem to have very little in common at first, they slowly begin to form a bond, with possible romance sparks in the air.
