Narration upon reading the passcode in the guitar in Dess's room, Chapter 4

The distance between two is the 46th track of the DELTARUNE Chapters 3+4 OST. It plays at several points in Noelle's House: in Dess's room, while the SOUL explores the vents, and in the living room after Susie and Noelle capture the obscured SOUL with a cookie pan.
