The wedding is finally underway in "Nisha Aur Uske Cousins" but not without a little dose of drama. Viraj (Taher Shabbir) barges in on Kabir (Mishkat Verma) and Nisha's (Aneri Vajani) wedding and openly tells the bride that he made a mistake. Viraj confesses his love for Nisha and expresses his regret at not believing her and her family.
Kabir, seeing how Viraj has come back, takes Nisha aside and asks her to rethink her decision of marrying him; now that the love of her life has come back, she need not marry him. Nisha remembers the number of times she tried to convince Viraj about her innocence and how he insulted her every time. She asks him to leave her alone as she now wants to marry Kabir.
In light of Nisha's decision, Kabir ask Viraj to leave the wedding and not create a scene. But Viraj picks a fight with everyone and before leaving, tells Nisha that if she is not his, he won't let her belong to anyone else.
After the whole wedding drama, Nisha and Kabir tie the knot, and the entire family relaxes and sets the stage for celebrations. In the meanwhile, Buaji (Tuhina Vohra) learns that Viraj and Kabir are stepbrothers. Viraj's household help Shaam Singh also learns about Kabir and Viraj's connection, but due to the fear of hurting his boss, he does not reveal anything. However, a major twist will take place when Nisha finds out this big secret. She learns that Viraj and Kabir are stepbrothers and that by marriage, she now belongs to the royal family.
With all the tension between Viraj and her, Nisha tries to keep this secret from her family. Telling her family would also result in confessing that for their wedding, Kabir had hired actors to play his uncle and aunt. What will happen when Viraj learns about his stepbrother? Will Nisha and Kabir move into the royal house post their wedding? Will Nisha be able to keep Kabir and Viraj from killing each other in anger? So much drama is still waiting to unfold but most of all, we are eagerly waiting to see how Viraj deals with Nisha's rejection and then his mother's betrayal.
