Even though it may be quite early to guess what will happen but I can't get this show out of my mind. With the current SBS/UMeTv/SBD segments that are being aired, it seems that Kunal will put forth the condition of eye surgery for Mishti. I hope on the day of the engagement, Kunal gets annoyed with Mishti due to her decision to keep her spectacles. Besides, as a cherry on top of the cake, Meenakshi should be successful in bringing up Naman's criminal past in front of everyone. This would make Kunal end the rishta. Abir can be shown to be protesting Meenakshi and Kunal's reason for breaking off the rejection at the engagement ceremony itself. Eventually, with this, Mishti will realise that Kunal is not the right choice for a life partner since he cannot accept her as she is and whatever she stands for.
After the rishta break up, Abir can then leave the house and go on his journey. Mishti, on the other hand, knowing Abir's decision to stand by her side against his brother and Meenakshi, will still be in touch with Abir and decide to continue working at his NGO. Kuhu and Kunal can also be shown to continue working together inspite of all that went between their families as you know Meenakshi claims that both her sons are professional and they wouldn't let their personal issues affect their work space. Then, they can show that Abir is still in touch with every Rajvansh family member except Kunal and Meenakshi. Even though Abir is aware of his feelings for Mishti, he decides not to confess because he wants Mishti to fall in love with him. Later on, as time goes by, Mishbir fall in love with each other. They decide to get married and go to the Rajvansh house for their acceptance of the relationship. Everyone is cool with it except for Meenakshi and Kunal. They decide to still get married and live at Maheshwari's place post marriage. Then, they can bring out the truth of Meenakshi's past and Abir's dad and Parul...and maybe this can prove to be a reason to unite Abir and Kunal together.
