Five girls in their twenties come to live together in a house called "Belle Epoque", which means "a beautiful era" in French.
Each girl has a particular personality, background, and issues. In addition to the five girls, they believe there is a sixth presence - a ghost living in the house, but each sees the ghost differently. As the girls feel a bond of sympathy and become closer, they also deal with their personal issues as they live out their eventful twenties.
The drama follows their struggles and incidents dealing with relationships - within their circles, with dating, and with each other - and a variety of events they are experiencing, including credits, part-time jobs, drinking, hopes and dreams.
