Raja Rani (2013 film)

John and Regina agree to marry each other for their parents' sake. After their marriage, they live together as strangers in their apartment, where the neighbours are upset with John, who comes home drunk every night from office, which John does deliberately to annoy Regina, who later applies for a transfer to Australia. One night, Regina falls due to fits, and John takes Regina to the hospital, where John is unable to respond to the doctor's queries about Regina's age and her medical history due to his intoxicated state. When John goes to apologise to the doctor later on, the doctor tells John that it is important to know about his wife's health, even if he dislikes his wife. John asks Regina about her health issues, and Regina reveals that she had fits twice in the past.

During college, Regina falls in love with Surya Muthuraman, who works in the call centre of a mobile company. Surya gets selected for airline cabin crew training in the United States (US), where Surya and Regina decide to inform their parents about their love, but Surya's father objects to their relationship, and hence they decide to get married without informing their parents. On the designated day of Surya's and Regina's marriage, Surya fails to show up at the registrar's office for the wedding. Regina's father, James, feels sorry for Regina and he takes her to Surya's house, where they learn that Surya has already left for the US. A few days later, Regina gets a call from Surya's friend Aiyappan and he tells her that Surya has committed suicide. Due to the shock of Surya's death, Regina suffers fits for the first time. 3 years later, Regina can't stand the fact that her father is in a mess due to her reluctance to marry and accepts the marriage proposal from John's family for Regina's father's sake, which leads Regina to marry John.

Upon hearing this story, John begins to like Regina and has immense respect for her, but Regina continues to disrespect John, until his best friend Sarathy comes to their flat and reveals what happened in John's past.

John, who roams around town with Sarathy, and goes to Keerthana's house to pick up a cheque on behalf of Sarathy’s uncle. John falls in love with Keerthana at first sight and roams around trying to find out more about her. Eventually, John finds out about Keerthana, but Keerthana rejects John's love after John assaults Keerthana's co-worker. However, it’s revealed that Keerthana loves John, but she never expressed it. John ties the knot with Keerthana a few days later. The day after their marriage, Keerthana dies in a car accident. This leaves John heartbroken, and he vows not to marry another girl again. 4 years later, Sarathy consoles and convinces John to marry again, which leads John to marry Regina.

Upon hearing this story, Regina also begins to like John and she feels sorry for his loss, as John witnessed Keerthana's death where as she had only heard about Surya's death. Even though John and Regina like each other, they never reveal it to each other. On John's birthday, Regina gives a gift to John and insists that he open it alone, but John doesn’t open the gift and throws it under the bed as he thinks that Regina is only pretending to be affectionate in front of James, who later witnesses this and thinks that John was acting affectionate with Regina in front of everyone. James tells Regina about John privately, but Regina remains confused as she genuinely has feelings for John, but thought John had feelings for her. Regina's request for the transfer to Australia is approved, and she tells him whilst he has a beer on the terrace. However, John tells her to go ahead with her plans, as he thought the beer was a bribe to agree to a divorce. Regina wanted to express her love for him on the terrace, and leaves heartbroken to the airport the next morning with John.

After dropping Regina off at the airport, John gets a call from Regina, who tells him that she saw Surya at the immigration counter. John rushes to the airport to meet Surya and tries to get Surya to accept Regina. Surya tells John that he was forced to leave by his father and that he faked his death so that Regina would get over him. Surya lies to John, saying that he is now happily married, and Surya tells John that a man cannot always marry the girl he loves, but a man can always love the girl he marries. As John leaves, Surya glances at the ring in his hand, which was gifted to him by Regina, showing that he will always live with the memories of their relationship and he will never marry another girl.

An angry Regina slaps him and admits that she never wanted to get back with Surya, since she loves John. Regina throws the gift that John never opened. When John opens the gift, he finds the words "Let's begin our life," and John confesses his love to Regina, and Regina says, "Brother, I already have a boyfriend," alluding to what Keerthana called John during their relationship, meaning that Regina knows about John's past. John and Regina realise their love for each other, and they reunite and begin their lives together.
