I think that firstly purvi will be mad and when arjun decides to yell the truth about his lady love. Purvi will see the consequences and sacrafise arjun. Arjun also understanding purvis position might even go ahead and remain engaged with ovi. Than Ovi Will Find out about Arvi and be heartbroken, and one of the many manipulative,sceehming, selfish chracters either punni or probably savita if/when Ovi Confides in her which she probably Will but she is going to be manipulated and Will start plotting against Arvi. I think that savita fits the bell for starters but later on Other chaacters such as punni,sacchin,( Soham perhaps) etc might join hands with savita-Ovi in their battle against poor Arvi. Ovi might use the situation and manipulate arjun och make him to feel guilty so that he does not dare to reveal his love for purvi. Than later on when arjun does tell Ovi about purvi despite all the tricks and guilty feelings. Ovi along with her gang Will try to make arjun to missunderstand purvi for some stupid reason. And we Will be back on square one with Arvi judaii. Silsila Jari rahega with arjun hurting purvi over and Over again. At the end i believe that purvi is the one WHO Will lose either way.
