So Anshuman left Preet because he don't want to kill her. He can't do this. He may started fake but Preet's pure and true love even changed Anshuman fake love to real love. Anshuman left her and now his loss had changed Preet from once tenderly lovable girl to hated dangerous women. Well apart their love really have a great influence on each other.
Like Anshuman said - Pyaar mien saath hona zaroori nahin hota but pyaar ka hona zaroori hota hai. (Not exact.)
18 years they both struggle and cry to their fate. Now when they met each other again their fate separated them.
Really both got destroy in this unsaid and incomplete love still have to stay separate.
The canvass of sadness and pain Preet shown after Anshuman revelation was so good. That instance change from hate to love was very nicely shown.
Anshuman on other hand is bind to Preet like forever even after staying away from her. Being near to Preet his body started giving up. That is really a great connection between this two.
Love their song it is perfectly match on them - Main tenu samjhavan ki. đ
Well done and in season 1 ending this two couple will stay in heart.
One is vampire and other one is witch still their love looks innocent.
