After a difficult breakup, Y/N leaves her ex and moves into a new shared apartment in the city, located in an old but renovated building. She doesn’t know anything about her new roommate, Cedric — a quiet, distant man who is hard to read. At first, life in the apartment seems simple and a bit unusual. Cedric keeps to himself, rarely goes out, and doesn’t talk much about his life. Y/N is just trying to rebuild her routine and move on from her past relationship. But over time, she starts to realize that there is more to Cedric than he shows and that living with him might not be as safe as she thought.
