There’s no reason for pari to get killed...radhika loves pari very much and mishty loves her sister. But ruhaan is not in love with pari...and we don’t like to see her going towards rejection. Because she’s going to be rejected and hurt. So she rather find out about mishaan and back off before letting ruhaan know about her feelings ,.because it will be humiliating for her and embarrassing for ruhaan. Ruhaan only sees her as a friend and he actually treats her like a little sister. but Arnav loves her and Bua adores her. So we would like to see Paris own love story with arnav ..Pari deserves happiness and Arnav will give her that happiness. I hope we get to see them together and happy before the end of the show.
