I found this sentence from the japanese yahoo answers:
男性は結婚して幸せでも、初恋の女性(プラトニック)のことを忘れられないものですか?
I think the sentence means: "Even if men marry and are happy, can they just not forget their first love?"

But I don't understand what (プラトニック) means for this question. Does it mean the man is currently in a platonic friendship with their first love? Or does it mean they never got past a platonic friendship but were still in love??
