Mouni discovers in the second episode that Debo is only interested in his navel and not in his personality. The next day he informed Ranjit about what had happened. When Ranjit and his wife Anchal had marital difficulties, he told them.
After talking about it, they found themselves attracted to each other and had a physical relationship. When Debo went out to work, Mouni and Ranjit had free time to themselves, but when Debo came home, he found his older brother with a woman he didn’t notice as his wife.
