DEv is doing the rite thing with Kjajjal
the mistake committed by kajjal is all because of her ignorance
and it bacame an unforgiven Sin on her life
as IF Dev would say that he forgive her he wont be able to even after they get married
coz Kajjal face and her presnece will alwayz bite Dev wat Sin she did
and itz not possibel for Dev to Survive with her
as how one love someone if the person itself whom u love is making u suffer every second and everlasting pain
By punishing Kajjal now Dev will be able to forgive her later
that will take a long gap but atleast Kajjal sufering will bring
DEv closer to her again
Now this will more salvation series for all to see
