From SBS clip, it indicates that Gunjan-Vihaan get engaged. This could be due to Vihaan plan successful in blackmaling Gunjan. There could be multiple reasons he was blackmailing. Gunjan is getting engages to Vihaan to SAVE Rachna. Vihaan has been consistently teasing Rajiv-Rachna and may have seen RR or the letter which Rachna wrote Rajiv...Also Vihaan is defaming Gunjan with photos..
So Gunjan will take all blame and agree to Vihaan. She will get engaged to Vihaan to save Rachna.
Later she will figure out how to handle Vihaan as breaking engagement is not big deal. She will teach Vihaan a lesson. May be Mayank will support her as he cant see them together.
Regarding my dearest RajNa, they are safe. May be Rachna is sad and runs out from the house in this eng fiasco and those sansrikiti protestor guys see her and kidnap her as they got abeating from Rajiv due to Rachna :). This incident may be added so somehow Rajiv will do all efforts to save her once again. He will indirectly show her he still cares :) and may be gets a support in him. This way CVS get to move story ahead, they will slowly develop relationship of mutually understanding couple...may be they will fall in love..and if SD is lucky her elder son will marry girl of her choice and eventually end mother-son feud..
Chalo...I am happy Rachna did not get engages to Vihaan as she would have ignored our Hero Mr. Rajiv Agarwal...completely..
There was sparkling in this eyes when he saw her and idiot congratulated her...Stop hiding your feelings and covering with good manners and great dialogues...
lets keep watching..
