Maverick Productions' Miley Naa Miley Hum is the story of a young boy whose parents are separated and who wants them to come together again. Chirag (Chirag Paswan) is saddened since childhood by his parents' separation. Right from his school days, he has to divide his time between his father, Siddharth Mehra (Kabir Bedi), and his mother, Shalini (Poonam Dhillon). Chirag now helps his father in his vineyard business and also helps his mother in looking after her huge business empire. Much as he tries to patch up the differences between his mom and dad, they refuse to come together and actually hate even the mention of one another's names.
Like his dad, Chirag also loves to play tennis but his mother hates the game because the father had avoided being by her side while she was delivering Chirag as he was busy playing tennis. So as not to hurt his mother's feelings, Chirag doesn't let his mother know about his fondness for the game but she gets to know about it.
One day, Shalini asks Kamya (Sagarika Ghatge), the daughter of her friend, to fly from London to India as she is keen that her son gets married to her. Around the same time, Siddharth promises Chirag's hand in marriage to Manjeet (Neeru Bajwa), the daughter of his close friend (Dalip Tahhil). Chirag likes neither of the two girls and is also aware that marrying any one of them would sadden the other parent. To get out out of the difficult situation, he lies to his parents about having a girlfriend. When asked who she is, he tells them, the girl is an upcoming model, Anishka Shrivastav (Kangna Ranaut), even though he doesn't even know her. To keep the façade going, he has to befirend Anishka. Soon, Chirag and Anishka actually get fond of each other. What happens thereafter? Is Chirag forced to marry Kamya? Or does he have to marry Manjeet? Or is he able to convince his parents to allow him to marry Anishka? What about his game of tennis for the championship of which he had been practising? And what about his dream of seeing his parents come together again?
