Where did you leave watching the serial midway, at what point?
You are too far behind..wayy behind buddy!
I hope some kind one helps you out, its way too detailed to explain..& I'm multitasking here, just in short- Bajaj-prerna are a very much in love couple now(atleast you can see the love for bajaj in preru's eyes very much now), facing ups and downs(kasautis) in their lives now, she just fell for him gradually( though some cynics still dispute it as an obligated marriage, crazy)..the leaps happened- 8 yr leap, 20 yr leap, now the 5 yr leap, kids grown up..onurag is happily 'very happily' married to his friend sam & moved on ATLAST.. prerna's son prem is supposed to be the lead but he comes across as the villain atm..bajaj is mia & preru is pining day in & out for her man..with onurag the good samaritan friend as usual helping her out...& komo mai creating her bakwas old misunderstandings...
man, just try reading the updates..else do a wiki search on kasauti!
Hope it helped!!
