"La Boheme" heroine
I believe the answer is:
mimi
'la boheme heroine' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mimi that I've seen before include "Puccini heroine" , "I'm upset twice by the operatic girl" , "I'm, I'm mad about the heroine in 'La Boheme'" , "Puccini's seamstress" , "unfortunate sewer" .)
