If you were aware of a commentary from before the 12th century that tells us it doesn't have a narrative, i would be very interested in that. The only ones i am aware of that don't see a narrative in Song of Songs are from the last 200 years

Does Gregory of nyssa, try to work out the narrative of the book? I.e. who is talking, the scene and how the story is progressing in each section?

Thanks for your response everyone - I am now reading through the recommended literature.

Question is now edited to be more clear.
