Living alone for almost three years is not a big deal for Kim Mina.  Mina’s parents were working and staying in New York since she graduated high school her parents allowed her to live alone but in a condition that she needs to stay on family’s friend’s apartment. She doesn’t feel lonely or alone because of her bestfriend Sohyun and his close cousin Kim Namjoon and his family.

Studying and working is not a problem. Time management is a key and also the people around help her to make life easy to Mina.

Mrs. Choi’s was an owner of four-story apartment building and Mina’s mother   second mom. First three floors were occupied and the fourth floor where Mina and Mrs. Choi is staying. There were still three door apartment that were available.

Mina’s always hoping that there more neighbor so that whenever she’s not around there are neighbors that can accompany Mrs. Choi who’s living alone. Does she feel the same way when her new neighbors will come will add spice to her life?
