I have no idea what it is meant to convey.
I have no particular idea either, but two things should clear things up, somewhat:
- At the end, we're given some bupkis information about "Adonis Syndrome" being an affliction that effects women... it doesn't exist... in that form at least.
ACTUAL Adonis Syndrome effects men, and is basically a body image condition, where the men are chasing their ideal physical form, much like Bulimia, but rather than just dieting, is usually through exercise to chase the ideal muscular form.
- Secondly, there's the flower language of the flower Anemone, which can have various means across the world, but the two that should be critical to this story is the European meaning of Lost Affection, and the Eastern meaning of Bad Luck or Illness. I think the Illness symbolism is the most critical here.
So the husband 'caught' Adonis Syndrome, and has basically transformed himself physically into someone the wife barely recognises. She wishes to see the old photo of the husband, but he's ashamed to show it, because of his body image issues. The flower symbology shows that the wife recognises that they're ill, but she's unable to broach the topic about it with him.
That's sort of the general crux of the story, as I'm seeing it, though I feel like there's a bit more here that I'm not quite picking up.
Could just be a case of trying to be deep while being quite shallow, as you can often get with newer authors; we're looking for meaning that isn't really there.
