Need help

Ok so I have not watched the show for sometime now
Can someone please tell me in breif what's happened
What has happened to Sakshi and is that woman
Devikas real mother and how did they meet

Thanks

Its not Devika's real mother as of now .. When Saket-Nivi-Manju aunty push Devika from the cliff , she falls in water and that lady rescues her and give her shelter .,. this lady only will give Devika new identity to take her revenge from her enemies

 Ravi and all thinks Devika died post leap .. But dunno the reality of her death yet .. they think its an accident ..

What happened to Sakshi and why she is locked in that room is a suspense still ..

Devika misunderstands Ravi thinking he is involved in her murder too but truth is Ravi is innocent and clueless about the whole thing .. he still loves Devika like crazy and to fulfill Devika's mother's dream of building a orphanage-school in that land , he is getting engaged to Nivi as Nivi kept a condition that she will start the school work on that land only if Ravi marries her ...
