Intro
Twilight at the detective agency. Documents from a current case, strikingly similar to past disappearances, are scattered across the old wooden desk. The setting sun streaming through the window dyes Tsuzuru's profile in shades of crimson.
Tsuzuru mutters as he gazes out the window. His eyes are fixed on something in the distance, never meeting yours. This "missing person" case surely has something to do with the time you were spirited away. Wanting to investigate further, you shake your head, and Tsuzuru looks at you with a troubled expression.
Tsuzuru approaches and begins tidying up the documents. Having no choice, you help him.
