Basically.. At the beginning it was Abha and her family living in Swarna Bhavan but something happened.. Im not sure what and I think the house got auctioned through which Karans dad bought the house (He was really mean back then and did it to seek revenge from Abha's dad).
Abha and Karan I think met in a hosiptal and when Abha and her family had no where to stay.. Karan helped her find a house (Karan didnt know that the house hes living in now belonged to Abha). And through the process of all this.. Abha and Karan fell in love <3 :D
Abha's mama let them stay in their house and at the beginning Abha's dad was against this coz he had thrown him out the house before.. He had stolen or something like that.. But now hes pretty ok with it as uve probably seen. Coz their family had no source of income.. Abha went to work.. At Swarna Bhavan.. Through which she got insulted quite a lot :( But Karan loved her and they married at a mandir.. :D
Abha's parents didnt know she was working at Swarna Bhavan.
Umm.. Then one day Karan and Abha were home alone and they had a romantic moment in which Abha put on this tape she found in a box (It was taken from the store room along with other stuff to be thrown away.. Basically Karan was not supposed to hear it).. So Abha put it on.. Unaware of this and a lullaby started to play.. They were dacing and all of a sudden Karan started getting dizzy.. He stated to have "fits" Like he was becoming all tensed and eventually he fainted at which point his family came home (Oh btw, at this point Karans family had lernt to accept Abha.. All but Shalini Bhabhi!).. They came home and told Abha she shouldnt have played it etc etc..
After this, Karan started to have kinda like falshback kinda things.. Like hed see things.. They were sent to Singapore for their honeymoon where this lady was following them.. We wernt told who it was till much later.. Later we found out it was PRATIBHA! Karans mum :)
Abha had taken Karan to a psychiatrist who had hypnotised him to get stuff he was seeing out.. Through which we were told that Karans mum had pushed his cousing off a terrace coz she had wanted to runaway with hr "boyfriend".. So Karan hated her for this reason.. She had left them to be with someone else. Obviously this wasnt true.. We found this out later.. Mama (who is now in prison) and masi had told lies.. Through all this Karans dad ended up marrying masi (i didnt see al this).. And somewhere along the line, Abha was able to expose mama and send him to jail.. but not masi.. :(
Karans mum came to his hometown and started following him ther, but coz she was aware that Karan hated her she didnt go home.. instead she started working as a maid at Abhas parents house.. Later they found out who she was and Abha and her mum worked together to get Pratibha the position she deserved.. And She did (I think) But somehow she ended up behaving as a child. I think she had an accident not too sure.. But yep.. And masi and her son and bahu and Shalini all tired to cause her harm but Abha was always there t protect her.
And then one day she was sent to the place she is now.. where thankfully she is getting better! But now all this "case 777" thing is out.. Prathibha doesnt know.. Ad im guessing you know and its been revealed.. Karan is "dead" :( and Abha is looking for him :(..
Ohh they had gone to Bombay t search for Ranchod Tiwari.. But masi and her son called Karan and got the papers signed and failed his brakes.. :( Im guessing u saw all this.. And thats all weve been shown so far..
