Five female university students share a house, called “Belle Epoque”, despite their different personalities. Jin-myeong is a 27-year old student who has finally made it to the graduating class. She spends most of her free time doing part-time jobs, but gains barely enough money to pay all her bills and repay a loan, so dating is out of the question.

Ih-na is the complete opposite, as she dates three men at once, because she argues that a carefree life is the best way to enjoy life. Ji-weon is a genius who receives many scholarships but also loves to party and is an expert in dirty jokes. Thanks to that, men have a blast when they spend time with her but no one ever wanted to become more than just friends. Eun-jae, the youngest among them, comes from the countryside and has just been accepted to join the household. She’s very shy and has no friend in her class, so she has a hard time adapting to the life in Seoul. One day, they start seeing ghosts in the house…
