The story then takes a three-year leap to start the new season where the group believes Nupur died by the hands of Samrat that day. Samrat, trustee of Excel College, has been living a disturbed and lonely life as punishment continually recalling Gunjan and death in between drinks; Mayank, in private industry, lives with the illusion of still having Nupur around in her void; and Gunjan, now grievance counselor, is internally, emotionally shattered. All three grieve the loss while the audience is briefed on the lapsed years. Ashwini, a new entry and orphan closely counseled by Gunjan, collides with Samrat and out of immense empathy helps past his guilt and Mayank eventually accepts a post for professor at Excel. At a point, both Mayank and Ash takes Samrat's advice to move forward. As the plot progresses, Rohan, a student, clashes and falls in love with Ash while other plot points unfold. Ash and Rohan both look up to Samrat and this is pivotal moving forward.

Now, Mayank questions Gunjan about being counselor at Excel. Initially angered, she eventually accepts because of circumstances. Meanwhile, Mayank begins forgiving Samrat as he realizes he was also responsible for that day. Samrat, now colleague to Gunjan, continually attempts, sometimes with Mayank, to make Gunjan smile again and move forward. In this, a play on Devdas is held where Gunjan falls in love with Samrat again but does not accept this. With jest or seriousness, the result of his attempts was multiplied heartache for both. On the day of the play, as a cameo, Diya reunites with Mayank to describe odd daytime premonitions about Nupur. On Diya's behest, they go to the administering doctor and find there had been a blunder in the chaos of that day and Nupur Bhushan might well be alive. Gunjan, now lost in life, shuns herself from comfort and hope.

After some investigation, Mayank and Nupur come face to face and he is certain his wife is alive in spite of remarks. While on a trail with Samrat and Gunjan, an emotionally incapacitated Mayank drives away alone and crashes into a tree. By fate, Nupur finds Mayank and sees him to the hospital where she signs the consent forms as Mayank's lawful wife. Eventually, the three find her and are certain of her identity when Nupur consistently and rudely refuses to recognize them. For misbehavior, Nupur herself comes to her home to apologize but they reply, if she truly seeks an apology she must reside with them for seven days. She agrees. In these seven days, as someone from the group gets close to Nupur and notices an anomaly a Private Number call breaks each effort and Nupur instantly becomes tense. The audience by now understands this is Nupur Bhushan.

On the fifth day, Dhruv, Nupur's fiancé, enters as the Private Caller. Dhruv physically and verbally abuses Nupur to a point where she emotionally surrenders to him. Although the trio fails to confirm Nupur as Nupur Bhushan, after a few days Gunjan suspects Dhruv to be grown-up Chintu, a psychotic boy from their childhood school that was admitted to a mental hospital. It was revealed to Samrat that Nupur was just pretending to not recognize them out of fear of Dhruv, who is possessive of her and Dhruv was the root cause of the car accident, three years ago. His intent was for the brake failure to kill Mayank, Samrat, and Gunjan while keeping Nupur to himself. Samrat then wants to disclose the truth but is forbidden by Nupur on risk of not seeing Gunjan or Mayank alive. Samrat then openly challenges Dhruv and conducts a plan where he sends Mayank to Gunjan's house, while Nupur is meeting Gunjan. Mayank talks to Nupur, which leads Nupur to cave and admit the truth. Everyone was very excited on this admission when things come to a boiling point.

Dhruv arrives at Nupur's house, as Samrat had expected, but is caught red-handed attempting to shoot and kill Nupur. With the help of Rohan and Ash, the police come out and arrest Dhruv putting an end to his track. Mayank and Nupur reunite at home after three years in their usual style, and Samrat and Gunjan attempt reconciliation. Gunjan uses the rekindled love after the play and the happiness from the adventure in obtaining Nupur to consider her relationship with Samrat mended. Nupur now rejoins Excel as a student to complete her studies, despite her dislike for studying. At one point, as things get tense and Nupur favors studying over romance, Mayank gives his class an exam. Nupur makes 'chits' to study, but unfortunately Mayank picks up Nupur's geometry box left behind in class with the 'chits' and assumes she cheated, justifying his accusation by pointing to Nupur's high marks.

While Nupur is at college, seeing everyone else's life back on track, Samrat decides to quit being trustee of Excel College and begins dreaming of basketball. In response, Gunjan, currently between being a friend and life partner, throws an MBA program on him and submits his application on his behalf. Samrat however lies to Gunjan to keep her pleased and begins an all-female basketball team that Ash takes a part in it. Samrat, upset with Ash bunking classes, forces her to get a letter signed that excuses her from class. Unable to reveal Samrat's secret team to Gunjan, Ash tries Mayank with no success so she forges Mayank's signature. Mayank, thinking Nupur also did this, rusticates her from the college. However, when Ash gets to know of this, tells Mayank the truth. Mayank feeling sorry for his distrust apologizes to Nupur but she does not accept it. On the other hand, because of Ash's confession, Gunjan gets to know Samrat is secretly coaching basketball confronts him about still attempting to lie to her face.

Now, the sisters are angry with the boys and the boys, knowing their mistakes, takes several different attempts to persuade them. Uday makes an entry here. Finally, after days, Mayank convinces Nupur before going to bed by pointing out today was their first date anniversary and they have a lifetime of fighting ahead of them. However, Gunjan under the impression Nupur had not patched up, stayed strong to girl power and continue rejecting Samrat's apologies. Uday now interacts with an unconscious elderly man in a wheelchair who won a '5 crore Best Family' lottery; telling everyone else he is dead and has a family who is in need of this money when in fact Uday wants to pocket it. Under a false pretense, everyone works together to enact the supposed family this man would have had for an inspector. This family happens to be an idealized version of what the gang already has: intense love, fighting, and an inept Dodo. While doing this Uday loses the money to the unconscious man and Gunjan discovers Nupur and Mayank are back to terms.

Now finally as things start to settle in life Gunjan realizes that she never deserved such an unconditional and persistent lover in her life. In fact, she feels she needs to apologize to Samrat for all of the times she has held him guilty for things he had never done. When apologizing on the night of Diwali, Samrat for the first time in three years notices his given engagement ring back on Gunjan's finger. Samrat then makes a grand plan to propose to Gunjan, which all goes sideways. Nupur finds out that she is pregnant and decides to hide it. Samrat finds Nupur's pregnancy strip and confronts her over the phone. Nupur finally reveals her pregnancy. At first, Mayank pretends to be angry but then he comforts her by saying that Nupur had gave him immense pleasure by telling this to him. Samrat proposes to Gunjan later that night in a very romantic, intimate, and heartfelt way and she accepts. They have a church wedding: a lifelong dream for Gunjan. Diya, Uday, and Benji return to the show for the wedding. After the ceremony, everyone goes to Pune where Nupur goes into labor and give birth to male twins. The show ends with the gang returning to Excel one last time
