However, things take a funny turn, when Murari rents out his rooftop room/ 'barsati' to Pancham. Elaichi makes Pancham her new target of pranks as she falls head over heels in love with him at first sight, while Pancham being completely unaware of this landa up working with Murari trying to make ends meet and reach his goal of becoming a music director. He moves to Delhi with his best friend, Pintoo. Since, Murari is principally determined to not rent his 'barsati' to bachelors, Pancham fakes being married and disguises Pintoo, as a woman posing as his wife.
