It's a bit tame, our love! (5)
I believe the answer is:
amour
'love' is the definition.
('love' in French)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for amour that I've seen before include "French romance" , "Affair of the heart" , "Affaire" , "(Secret) lover" , "A secret love affair in France" .)
