look kriya left on a bad note---she hurt him deliberately, so he would forget about her and move on.
then rey was healed by taani---and taani is gone too.
i do not---repeat not think----that swayam would have told that much about rey and his own sisters relationship to a girl who is his friend and still madly in love with rey.
and call it a brother's drive to ensure his sister's happiness...swayam knew kria loves rey----but he did not disclose this to rey i think, coz he wanted taani happy...and rey was happy with her----all hunky dory---by bringing in a girl who had vanished off the face of d3 he would most certainly not risk taani's and rey's relation.
so she still loves him
and somewhere----rey has not really forgotten her. he was angry with her, hurt---and thus fell in love with someone who loved him back.
but seriously, kriya understands rey and his passion better than taani ever could...and taani found her perfect life partner in vishesh----settlement, security and understanding patient love---and she will fall in love with that life.
but rey and kria----they have a different bond-----.
love is not always enough. a life togetehr needs more.the ability to understand each other perfectly, and keep each other happy.
kr is just that. often i have found this missing even in swaron...they keep becoming rocky time and again.
