Overwatered Chilli plant

A few days ago I had accidently overwatered my chilli plant and subsequently it was left standing in water for a day. I have resolved that problem but now about 60-70% of the leaves have dropped off and a few of the flowers have curled up. I assume I managed to suffocate/rot some of the root structure. Is there any hope for it making a revival? :(

 

yes, if you keep it well cared for I would say it will recover
