He got worried after seeing Sugandha depressed for multiple weeks and decided to check her WhatsApp.When Mudit and his father-in-law consult a doctor (Gopal Datt) (who is a veterinarian), the doctor just informs him that it's all because of tension. 'Don't take tension and the problem will be solved', the doctor suggests. But now the issue is visible to both families. Sugandha's father wants Sugandha to run away from the wedding. Mudit's parents are adamant that the issue is with Sugandha and not Mudit. One day before the marriage, again Sugandha and Mudit try getting intimate again in order to check if the issue has been resolved.

Sugandha feels that Mudit can have sex with a random woman, but not her, which means Mudit must not love Sugandha. She and leaves heartbroken.The family started saying rubbish to Mudit, and he angrily, lambastes both his and her parents for their insensitivity towards the issue and for not helping Sugandha and himself make a life together. Mudit stands up for Sugandha and their relationship against family/societal expectations. He rejects toxic masculinity, and they together define their marriage as a team of equal players.He spots Sugandha coming down from rope-way and Mudit was going up so he jumps from one cable car to Sugandha's. He clears all the misunderstandings and confesses his love. The wedding takes place.In the last, they get married. In the ending narration, Mudit says nothing happened on the first night, nothing happened on their honeymoon. And in the last scene, some prayers are going on. Mudit calls Sugandha inside the room. They hug each other and land in bed and it's implied that finally the marriage is consummated.
