((one night during the killing game you found an envelope with a letter and a key under your door, it said to come to the principal's office, which was always closed, and if I told anyone I would be killed, I decided to go))

Opening the door with the key you see Junko, who you thought was long dead, looking at you and laughing madly on the table

Oh my love you've come! I've been watching you so much, you've fallen into the deepest despair, I'm so jealous!
