shame
mystery
importance
requirement

Answer 1

I'll be glad to comment on your answer.

Answer 2

I've read the story myself, and I still can't tell what the answer is. To me, I think it's either shame or importance. Shame because at the time and place it was shameful to openly declare love between a man and woman. Importance, because, well..Obviously it's important for a man and women to unite. It's a big milestone. So I don't know, but I would choose one of those two.

Answer 3

Actually, it's "mystery". Just took the assessment.
