I don't know where u hav seen from so i will just start from da beginin
Heres it briefly
Sujal n kashish work together, typical middle class girl with a rich boy, they fall in luv but under family pressure'😭'😭 kashish marries someone else, piyush, who is also sujal's frind. Sujal can't tolerat this so he tries to seperate them but they became closer. Then piyush has a accident n dies n with some evedence kash thinks sujal killed him(but he didnt) n sujal asks kash to ammry him, she at frist says no but then to take revenge she marries him n finds out he is innocent.
After sujal n kashish got marrried alot of things happend then they started livin happily'😛'😛, then sujal has a accident n evry1 thinks he dies but actually he comes back with plasticsurgery, n coincidentaly he comes back as tushar to the garewal house n falls in luv with kashish but kashish doesn't recognise him but eventually he makese a place in kashish's heart n she agreed to marry him. but then she finds out charu(her sister) luvs tushar but she can't do anything about it then on her wedding day she finds out that sujal'😃'😃 is alive but she doesn't know its tushar. then iqbal khan enters pretending to be sujal who is paid by swayam. n tushar has to marry charu cuz kashish wanted him too n charu faked that she was pregnant with tushar's child. Later kashish finds out that da sujal she's been livin with is not sujal. Then eventually she finds out that tushar is sujal but she tells him to go to charu cuz she is pregnant, then charu pretends she has an accident n loses her baby(to end this lie), so then she had to come up with a new plan to get sujal so she pretended that she was disabled n she cud't walk. Later sujal finds out she was lying n he leaves her. oh yeah i forgot to say that kashish was pregnant with sujal's child n she didn't tell him, but he also later finds out n kash n suj were startin to come closer n charu cud'n tolerate that so she commited suicide. After that kashish thinks cuz of their luv(kash & suj)charu has dies so she decides not to go back to suj, but suj tries to get her back, then kashish finds out charu was murdered n she tries to find out who it was, n in this case she got married to aluwalia to find out who da killer was. so then he was drunk one night so he took kash in his car n they had an accident n they lost their baby so suj felt guilty later but got over then started hating kash for betraying him so he pretended to fall in luv with aluwalia's daughter,gayatry, to make kashish jealouse, n kashish tried to seperate them thinkin that suj is not gud for gayatry cuz he just wants revenge. And later aluwalia dies n da same person killed him who killed charu.And da killer is already shown, its siddhart, mauli's(kash's sis)husband.
Now suj n gayatry r gettin married n suj wants kash to come to his weddin....
