On her wedding day, Vidya finds out

On her wedding day, Vidya finds out that
Sagar is mentally unstable, having the
mindset of an eight-year-old due to an
accident that almost claimed his life. Sagar
does not realize he is married; he and Vidya
get off to a rocky start. Sindoora, Sagar's
evil stepsister, arrives and confronts
Rajendra about the marriage, leading to his
heart attack and death. Sagar becomes the
sole heir to the Pratap Singh fortune.
However, Sindoora wants the Thakur
property to herself and will go to any height
to gain it.
Sindoora's other two sisters are Mahua
(Himansshi Chaudhary) and Chandra (Addite
Shirwaikar), who do whatever Sindoora tells
them to do and continually harass Vidya.
Vidya is not alone: Sindoora's husband
Aniket is on her side. Sindoora's son Bharat
is closer to Sagar than to his own mother.
Aniket knows Sindoora is evil and tries to
bring Vidya and Sagar closer together. This
proves to be a difficult task as Sindoora is
continually plotting against Vidya, even
trying to prove that Vidya attempted to
poison Sagar. Slowly however, Sagar accepts
Vidya and calls her his best friend. Their
relationship blooms and he falls in love to
the point where he can't live without her.
Sagar and Vidya's love is blissful and
beautiful, however, Sagar is still in the
mindset of a child. Vidya learns of a
hospital that can cure Sagar. She gets Sagar
to the hospital.He has an operation and
becomes normal again — with a horrible
catch: He only remembers his life before
the accident, not after it. This means he
doesn't know that he is married and refuses
to acknowledge Vidya as his wife.
He returns home, where the Thakur family
are delighted to see him back to normal.
Vidya arrives as well, refusing to accept
defeat. Sagar reluctantly lets her stay and
finally remembers that Vidya is his wife and
that they had fallen in love. He also
remembers that his accident was not an
accident at all — it was planned by
Sindoora, who had been trying to murder
him to take his property and fortune.
Sagar and Vidya try to escape Sindoora's
wrath but, soon enough, she corners them
on the edge of a cliff and points a gun.
Vidya is shot first; Sagar second. With his
last breaths, Sagar tells Sindoora that the
story is not over and he and Vidya will
return. Vidya and Sagar drag themselves
across the ground to each other but, before
their hands can meet, Sindoora shoots them
again, finally killing them.
21 Years Later: Amar and Divya
(Reincarnation of Sagar and Vidya)
Sagar and Vidya are reborn the very night
of their deaths as Amar and Divya. 21 years
later, they are now the complete opposites
of what they were in their previous lives:
Amar is a spontaneous tour guide in
Beneras and Divya is a modern woman from
the city.
Sindoora is introduced to Divya after she
makes a dramatic entrance. The family is
shocked at Divya's resemblance to Vidya.
Divya and Amar meet in Banares in a similar
way they met in their previous births.
Though they get off to a rocky start, they
soon become friends and, as fate would
have it, fall in love. Eventually, they get
married and destiny brings them back to
the Thakur household. Divya and Amar get
frequent flashbacks of their previous lives
but neither actually remembers until
Sindoora shoots Divya. Divya survives and
remembers everything from her previous
birth, also remembering that Sindoora is
their murderer.
Divya tries to prove to Amar that Sindoora
is their enemy and the cause of their
previous death but Amar refuses to believe
her. Eventually, Amar also remembers his
previous life and who Sindoora really is
after she attempts to murder him, too.
Bharat, Sindoora's son, who had ran away
21 years ago at the time of Sagar and
Vidya's death as he had realized his mother
is evil, returns to help Amar and Divya get
their revenge. With Bharat's help, Amar and
Divya are able to overthrow Sindoora.
During their battle, Sindoora falls into a
lake and, though her body is never found,
she is presumed to be eaten by crocodiles .
Amar and Divya embrace their new and
happy life, and Divya becomes pregnant.
Sindoora re-enters their lives as it turns out
she was never dead. Sindoora harms Divya
while she is pregnant, causing Divya to go
into a coma after giving birth to a girl, Dia.
Divya recovers from her coma, but
Sindoora works her many traps on them,
making their lives like hell. Her evil
workings cause Amar to be sent to jail and
sentenced to death. Sindoora kidnaps their
baby daughter and hangs her from the
branch of a tall tree, threatening to drop
her from that height and kill her. Divya has
no idea what to do: On one hand, her
husband Amar is seconds away from being
hanged and on the other hand, her daughter
Dia is at risk of being killed by Sindoora.
Bharat calls the police at the last minute
and they arrive to see Sindoora keeping the
baby dangling from the tree. They realize
Amar is innocent; as he is 30 seconds away
from being hanged, they call the
executioner and stop everything. Amar is
saved and Sindoora is finally sent to jail.
Epilogue
Sindoora goes mentally crazy in prison, just
as she had rendered Sagar so many years
ago. Divya and Amar have their wedding
again with the entire family present.
Sindoora's evil reign has finally come to an
end after more than 25 years and Sagar and
Vidya (as Amar and Divya) are at peace. The
series ends on a beautiful note as Amar and
Divya finally get their fairytale happy
ending.
