Can leaves recover from "droopyness"?

[NTN]

I recently got my first orchid (phal) and after 3-4 days the leaves started to droop. I don't know what I did wrong but for now I moved it away from the window.

I watered it once before I knew that you shouldn't let water sit in the crown. I used the shower hose and let water run through it until the media was completely soaked. I then let the water drain through the holes of the plastic pot and I put it back in its decorative pot.

How sensitive is the plant? If I let water remain in the crown once would it take any damage? Is it possible for the leaves to perk up back to their initial states if I take good care of the plant?

Also, even though the leaves started to droop one of its buds are starting to bloom. Could the blooming bud be responsible for the droopy leaves?

Thanks.
