Just trying to explain as possible as I can..
At first
Archu has one Rishta from Satish Joshi..And all Ks are happy..When Satish n Archu goes to date on one day...Manav see archu and fall in love with her...
Ajit is thinking how to take revenge?? He makes a plan..Ajit do things one by one So that Satish thinks that archu is a prostitute...Once Ajit sends archu in 'Badnam Gali' and also sends Satish to confirm that...Satish is really shocked and breaks the relation..But Manav save her from that badnam Gali...At home Due to this archu attempts a suicide in frustration..All family members are worried..Next day Manohar also attempts a suicide..From that also,Manav saves him..When he ask reason to Manohar, Manav came to know that This man is archu's father...
Now Manav is thinking how to imperss all K's..He makes such a drama that all K's think Manav is very rich man, having lots of money and his own garage.. After a long period he gets success in convincing them...This continues upto the marriage..At marriage Sulochana came to know all the truth...And she makes a huge hungama..But it was too late...Manav already had put sindoor...Savita gets very very angry due to this drama..Marriage breaks..Then both are at their home remembering marriage moments..One day Manav's kaka arrived and they convince K's that Armaan are made for each other..So Sulochana sends her to Deshmukhs...During this time Manav came to know that the man who framed Archu is Ajit...He threatens him and tells him that he will reveal his true colours...But when he reveals the truth Ajit make such a drama that all situation is get reversed and all the blame comes on Manav...Now this time no one believes Manav...Not even Archu because ajit gives false proofs..Again huge drama...Archu leaves deshmukh's home.
Meanwhile Satish is introduced again and Bhavana aai wants the relation again...On other hand Manav is try to prove his innocence..But archu didn't believe him..In between these, Sachin And Shravni fall in love...And decide to marry..And after marriage they decide to go to London..
Manju and rasika creat such a scene that Manav thinks that archu is marrying Satish...So Savita aai gives the idea of divorce to Manav...Manav isnt ready he says he believes archu...Now this time Savita makes a huge scene...After watching all the scenes created by Rasika and Manju Manav signs the divorce papers in frustration..
Archu is shocked that Manav has signed the papers..Because she has a little faith in Manav...But when she asked Manav about the signing the papers he tells her that "YOU AND SATISH ARE FREE TO DO ANYTHING NOW"...Archu is shocked by hearing this...And she also in frustration signs the paper...
Damodar isnt happy..Then he makes a plan to proove Manav's innocence and he records Ajit voice in which he is saying that "he framed Archu n not Manav"...Manav is really happy now...But Manju and Rasika makes an false complaint on behalf of Archu of harassment of Archu against Deshmukhs..All Deshmukhs sent to jail..Now Manav is very very angry, breaks all all all relation with archu...
Due to this jail matter Sachin's Visa canceled..He died accidently...All Deshmukhs blaming on Archu except Damodar...
Then Shrawni tells Deshmukhs that she is pregnant with Sachin's child..So Manav decides to marry with Shrawni for the sake of her child..
On Court hearing day Damodar gives the tape to archu, Archu is shocked....and says NO to divorce and court tells them to live 3 months together...Manav is very angry now...damodar is happy..
Archu decides to go to Manav's home and tells him that she loves him a lot..And now she know the truth that ajit was behind all this..also tells him that she is here to rectify her mistake..
Manav also shocked..But tells her that situation are changed now..Archu left shocked..But then because of court order she decides to live there..She says if Rasika or Manju can object this and they can again make the compliant..Manav also ready for that..But Savita doesn't...She is very angry with archana....
She make archu life hell there..But archu did such a thing one by one that she completely turns her hate into love..By the time when the period of 3 months get completed they face their divorce in a sad manner...
