Second strong reason for it it dat Onir is shown to b positive n his track is still going on...if it was end of road for Onir den his character would have ended abruptly...but again n again showing him as a super duper tyaagi n positive character simply means dat PuNir will b together...
above 2 reasons r valid only if Leap happens.
P.S. well its useless to say dat dis post is not meant to b a ArVian..Arovian or punir post coz i know all aashiques of these couples will jump here n start bashing...but who cares...as far as i am concerned herein i've jus came out wid storyline.. no jodi making or breaking business
