On the day of her first wedding anniversary, Rosy, under the pretext of running errands for their party, travels to Los Angeles from her home in San Francisco without the knowledge of her husband Jackson to meet Rocky, her former lover.
One and a half years ago in San francisco, Rosy is a student who wishes to make a recording of a dance performance so that she can show it to her family post marriage. However, a lack of natural talent forbids her from doing so. Rocky, a young statistics student, is an orphan whose godfather Michel, happens to be the principal of his institution. Rocky wishes to pursue a Ph.D. in his subject and settle in life. Rosy happens to spot him dancing at a friend's wedding and requests him to teach her. Rocky agrees for the large fee she offers as he is in need of money. He helps her, not only with her dancing but also with other issues, including confronting a bully who torments her. Rosy wins a dancing competition and the two realize they are in love with each other.
Rosy tactfully clears the penthouse her family owns so that Rocky can stay in the same house as her. Rocky starts giving tutoring classes in the penthouse and earns the money he requires. When Rosy's family starts looking for marriage alliances, she requests Rocky to elope with her, and he reluctantly agrees. However, a chance encounter with Rosy's father, Thomas alpha, makes Rocky realize that he is ineligible to marry her as he hasn't fully settled in life. Taking this to heart, he requests Rosy to allow him to go to California and get a Ph.D., thereby securing a future for both of them. Rosy allows him tearfully, and he leaves for California. For the next few months, she continuously ignores Rocky, who keeps trying to contact her. She is soon approached for marriage by Jackson's family, and her family agrees. When Rosy contacts Rocky, she realizes that she is not ready to take the guilt if he blames her later on for the failure in his career, and unwillingly marries Jackson. A year later, Rosy is contacted by Prof. michel who informs her that rocky has gone into depression and is now an alcoholic. He is on the verge of being fired by his firm in Los Angeles and is spiraling toward a self-destructive path. Feeling responsible, Rosy travels to meet Rocky.
Back in the present, rosy tells Rocky that she is happily married to Rocky and does not wish to go back with Rocky. Rocky objects saying she still loves him and is leading an unhappy life. Back in San Francisco, Rosy tells Jackson about her encounter and tells him they should call Rocky to their house for 10 days so he can see how happy they are. She contacts Rocky who tells her that if he fails to see the love between her and Jackson, she would have to go away with him. Rosy, initially hesitant, agrees. Rocky lands in San Francisco, and immediately strikes an awkward relationship with Jackson. He repetitively irks the couple and mocks their relationship, which annoys Rosy. However, Jackson's colleagues take a liking to Rocky, whose pessimistic nature offends a few other people. This is soon disrupted when Thomas alpha and his son-in-law, george binto unexpectedly land in San Francisco. Rocky is introduced as Jackson's old classmate and is made to promise Rosy that he would not reveal his actual reason for being there. Thomas alpha reveals to Rocky that the daughter of his friend committed suicide after having been married off to a man she doesn't love instead of her lover. He had come to know on the wedding day that rosy had a lover from shiny, rosy's best friend. Doubting that Rosy is unhappy with her marriage, he came to San Francisco to find her former lover so that he could get them married if she wanted. Rocky, realizing his advantage, indirectly begins to coax Thomas alpha and george binto into finding the truth themselves. When shiny is interrogated, she covers up with a fake story saying that the lover is married and herself tells her father that she is happy. They all go for a trip to Santa Monica for jackson's business meeting. There rosy discovers that jackson is having an affair after seeing him hug another girl secretively in the parking lot. Thomas alpha too finds out about Rocky from a phone call with jackson's father and shiny. rosy confronts jackson, who lies to her again, confirming to her his infidelity. She confides in Rocky, who believes she now hates Rocky and wishes to be with him instead. However, when thomas alpha tells Rocky that he wishes to get rosy married to Rocky a few days later, he tells thomas alpha about his encounter with jackson. Having been an introvert since childhood, jackson's first friend was Christie, who he met during his MBA. Her attitude towards him makes him feel he has found a best friend. She unexpectedly proposes to him one day, and he rejects her replying that he has never seen her in that way. He begins to avoid her and soon finds out she is now a drug addict and has attempted suicide. His guilt persuaded him to allow rosy to call rocky, as he believed rocky also was heading in Christie's direction.
rocky realizes that even though rosy can still be his, it is only right that she stays with jackson. He forces thomas alpha and stages a play where he himself looks like a negative person to rosy and coaxes her into realizing jackson's honesty. jackson prepares to leave the house, believing rosy would be happy, but she does not allow him to do so, and they clear up their misunderstanding with jackson telling rosy that he loves only her. As they embrace at their reunion, rocky is heartbroken and walks out of the house, crying and shattered. A year later, he arrives in sanfrancisco and meets rosy and jackson, who now have a daughter, and reveals he has come to meet a girl he met online, hoping to settle and marry.
