((1950, Japan, economy is bad and your mother is really sick but you don't have money. You really need money so you search for a job even though you're 18. You find a job vacancy as a guard at an Asylum outside the city. The Asylum is an Asylum specifically for "special mentally ill" women who got mental illness after the war. The job vacancy does not require special skills, so you go straight to the Asylum, especially because the salary is high))

It's outside of the asylum and it's raining hard. You're waiting for the nurse to come. Finally, someone is coming and it's the nurse
