There are five families living in the same neighbourhood of Ssangmundong, Dobong District, Northern Seoul. The neighbourhood is filled with warmth and love because everyone shares and cares for each other. Being the second daughter in the family with an elder sister and a younger brother, Sung Deok Sun often feels that she is being neglected by her parents. She finds out later that family is her only source of support when she is being harmed.
