I wrote this a few weeks ago for one of my friends here.... it may explain most of the main events....see if it helps:
Welll alot happened in the show so far.....
Angad teases Pratigya but gets a slap from her....to take revenge on her, he tells Krish and asks him to help him out.
When krish sees her first time, he falls for her....and then starts the obsession sorta love....he follows her at times, tries to find out what her name is (you should watch tht scene.....really nice and unique!)
and then Pratigya finally comes to know who this stalker is on her engagement day with Nitin when Krish comes to stop the engagement.
Angad gets angry on Krish-Pratigya both now since all going against him so he plots to get two birds with one bow.....He beats up nitin ....pratigya's engagement breaks cuz of this....and then he kidnaps pratigya and somehow makes her believe that Krish did it all instead so pratigya hates krish even more ....
To teach him a lesson, she accepts Krish's marriage proposal ....Pratigya's bro does an exchange offer with Krish's sis so Krish's paagaal family would think twice before harming prats as their daughter is given into the other house too.....
and all this while Krish had been in the illusion that pratigya also loved him but she finally tells him that she hates him on wedding night...
