With the passage of time the two get married. Both Ayaan and Ahana are looking forward to a happily married blissful and contented life. But the future has something else for them.

Things are "hunky-dory" until Ahana discovers that there is vast cultural difference between her upbringing and that of Ayaan's family. Small differences crop up which eventually lead to major confrontation between the two. Can down-to-earth and strong believer of a united and happy family, Ayaan, maintain his cool and bring his wife and family under one roof? Will good sense prevail on Ahana and bridge the differences?
