Tara and Adi speak to Gopi about their proposed living arrangements. Tara says that she will eventually leave for her architecture course in America, and hence this is a temporary arrangement.

One midnight, Tara has a conversation with Gopi. She tells him that she might get her visa approved for going to Paris, and that it's hard for her to leave Adi and go far away. She says that 6 months ago she was very sure about pursuing her career, but now she is in 2 minds. The next day Tara goes to Jaipur for her business, and Adi starts to miss her terribly. When Tara comes back from her trip, Adi was gone for a few days. She learns from Bantu that Adi goes to very dangerous places in Mumbai to do some authentic research for his video game, to make it look realistic. Tara is livid with Adi for taking on such high risks with his life. She realizes that she really cares for Adi. Upon seeing the love and patience his house owner Gopi has for his wife, Charu (Leela Samson), an Alzheimer's patient, who one day even forgets the way to her own house, they begin to understand the importance of each other's presence in their life. Tara's mother finds out about her live-in relationship with Adi and takes her marriage proposal to Adi's brother. Tara is livid at her mother interfering in her life and putting spies on her. Tara's mother says that she is being considerate by accepting the boy that Tara has selected for herself. Adi's game concept is a hit. Soon, Adi is selected to develop his skills in video games and to go to the United States. He tells his colleague that it's hard for him to leave Tara. The next day, both of them make an agreement to enjoy themselves to the maximum for the 10 days left before they separate. Nearing the last day, they begin to have little fights and arguments, which don't last long. One day, Charu goes missing again, as she did when she forgot her house address.

Post marriage, both of them continue to accomplish their own dreams, one in Paris, another in US. And they live happily married and in love.
