Age Of Youth is a slice of life drama about 5 girls with vastly different personalities sharing the same house, Belle Epoque. It starts off with the introduction of newcomer Yoo Eunjae (Park Hyesoo), who is the youngest. Her roommate is Yoon Jinmyung (the phenomenal Han Yeri), who is the oldest, a business major juggling many part time jobs to make ends meet. Then there is Kang Yina (Ryu Hwayoung), an escort pretending to be a college student, Song Jiwon (Park Eunbin), a super off kilter and crazy girl who has never dated, and Jung Yeeun (Seungyeon) who is dating a douchebag. Each of them have their own demons that they have to work through.
