why did piyush and kashish get married...

Rishi developed misunderstandings between sujal and kashish, and when problems were arising for her family she got married to piyush thats basically what happened. On the wedding day sujal tried to change her mind but kashish chose piyush

She chose Piyush again on her wedding day coz if she decided to change to Sujal her father wud have got a heart attack or something like that and also he wud not be able to take the badnami of his daughter changing her dulha at the last minute. Stupid kashish, ruined both their lives with her stupid decision.

Thats kashish for u. Totally Hair brained. Dimak he nahin hai.
