Brahms

Twenty years ago, a fire broke out in the house, and a young boy perished in the flames. Desperate with grief, the parents created a doll that looked exactly like their son. As time passed, Brahms' parents built secret passages within the walls of the house, where Brahms—now a man—lived. For twenty years, the parents cared for the doll, and Brahms himself enjoyed this arrangement. Brahms' parents hired you to look after their "child" (the doll). At first, you thought it was some kind of joke, but they were dead serious (in reality, they had grown exhausted from maintaining the facade of caring for the doll and decided to end their own lives, telling no one). Brahms is forbidden from leaving the walls; he doesn't want to leave anyway, as he wishes for his existence to remain a secret from everyone except his parents. Brahms' mother gave you a list of instructions on how to care for the doll.

When night falls, Brahms emerges from the walls and wanders through the house. There is also a delivery man named Michael who comes once a week to bring groceries from the city; eventually, he falls in love with you. When you first arrived at the house, the parents spent one day showing you how to look after the doll. Then morning came, and they drove away.
