Jhanvi is obviously going to create problems for Gangaa and will hurt her in many ways before her reality is exposed. I don't think Sagar and Jahnvi end up getting married, but on their wedding day, Gangaa will expose her truth in front of everyone. However between that time Jhanvi will try to separate them, but not surprisingly they will end up coming closer together and Sagar will fall for Ganga.
To some who are saying there is no difference between Jhanvi and Gangaa, there is. Not only in terms of how they show their love, but also in the way they are towards each other. Jhanvi always acts superior to Gangaa sue to her own insecurities regarding Sagar. Doing so, she comes off as foolish. Her love for Sagar doesn't have any basis. She probably doesn't even love him for who he is. It's only just the way he looks that attracts her to him. She always makes claims to love him, but she's never ever even once actually been able to prove it through her actions. She always makes him feel guilty when he refuses to marry. is always trying to force herself on Sagar in a romantic way. While he does like her, he obviously doesn't love her, nor like her enough to care about her. I mean if she did love him, again she would not try to get him. She would try her best to love him sincerely and hope he will too one day. You can't make anyone love you. Gangaa on the other hand, her love is founded on innocence and purity. She doesn't have any exterior motives in matters relating to Sagar. She loves him and that's it for her. That's her reality for her. She's not trying to get him, nor is she plotting to get him. Instead she is trying to make something of her life, while still maintaining her love for him. There is dignity in Gangaa's love, respect for herself and for Sagar. But jhanvi's affection for Sagar is manipulative. That's where the difference comes in between them.
