東北一家人媽媽4.0

　　Jina is the top employee at a credit card company call center. She avoids building close relationships, choosing instead to live and work alone. One day, her irritating next-door neighbor who would attempt to talk with her is discovered dead, several days after having died alone in his apartment. Jina is shaken and turns on the home camera installed at her mother’s house a long time ago.
