Chaaru & Maayank celebrations in the beginning (I am saying celebrations because I don't think there engagement or even engagement preparations started yet, it it did then Maayank Chaaru engagement)
Gunjan & Maayank engagement and other rituals
Rachna & Vihaan engagement and other rituals
Chaaru & Maayank rituals and again engagement
Gunjan Aditya engagement and rituals
Gunjan Aditya wedding
ALL FOR NOTHING. I mean the money related problems, they wasted a lot of money yes, but most of them taught the characters something.
Chaaru and Maayank wedding: One positive thing about this is Seema and Sangeetha learned their lesson and saw Chaaru's true colors. Maayank was getting punished for his behavior.
Rachna and Vihaan broken engagement: Rachna got much more stronger and this led to Vihaan falling for her. Vihaan is now a better person and he will soon repent his mistakes.
Gunjan and Maayank broken engagement: We saw that Gunjan kept her self respect and turned down Maayank, and we saw Maayank get punished for his behavior. This led to Chaaru Maayank wedding where Seema Sangeetha learend there lesson and saw Chaaru true color and start to like Gunjan. It also made Maayank think 100x before doubting Gunjan now. We saw him say for himself during Vihaan Gunjan Rachna drama, "I made the mistake to doubt you once, I am not doing it again."
Gunjan and Aditya drama: I have no idea what they are gonna show now
