Getting fed up, Shikha arrives back home, when she sees how close Sameer and Sanjana have gotten within 15 days she gets jealous, causing an argument with Sameer and the two break up. She then starts friendship with Sameer, after his boss arranges for Sameer and Sanjana's wedding. But before the wedding Sameer eventually realises he truly loved Shikha and can't live without her, so he breaks the marriage with Sanjana.

Taran Adarsh of Bollywood Hungama says "On the whole, DAMADAMM isn't bad, but it isn't great either. Though it has a hit score to its credit and some endearing moments, it will have to rely on a strong word of mouth to withstand a mighty opponent [RA.ONE]."

Dainik Bhaskar reviews it as "The story is simple, predictable with pinch of humour and emotions. This love saga is something anyone would have watched millions of times, however, what's noteworthy is the placement of the sequences which are successful in letting the story be a simple one and not complicating it further".
