The transcript related to the Hospital Harem route. I don't see what else you could have possibly thought this transcript was about.
Note that this transcript needs you to be at floor thirteen or deeper of the Dungeon to start it.
This transcript will NOT cover the enslavement of Dr. Tiff - only the scenes that happens during the actual route, meaning it starts when the Protagonist walks in on Dr. Tiff about to enslave a student.
