Yeh Un Dinon Ki Baat Hai

Naina is caught in a dilemma. She cannot tell her parents that a chewing gum is stuck to her hair nor can she cut her hair to get rid of the annoyance. Finally she decides to cut her hair off to remove the chewing gum. But, what happens when her family finds out about it?

Naina's new hairstyle catches the attention of her family. Bela is blamed for not having disciplined Naina. Sameer and Naina come across each other in the market but do not really meet. Then, when Sameer goes to the school, he immediately becomes popular. Will Sameer and Naina meet each other this time?

Naina is on a quest to find the meaning of a certain song. This quest lands her in all sorts of troubles as she gets rebuked by her family members. Sameer’s mother, Vishakha, wants to get him enrolled in a boarding school. But, her father refuses to let him go. Vishakha then bids adieu to Sameer, who is happy that he will be staying with his grandfather. Then, the situation for Naina gets a whole lot troublesome as her family members find a love letter in her notebook.

Sameer meets the school principal, who approves his admission. After the meeting, Sameer accidentally goes to the girls' washroom in desperation. Suddenly, Naina walks into the washroom and is stunned when she sees Sameer inside.

Naina sees Sameer for the first time in her school. The time seems to have slowed down for Naina as she feels an inexpressible emotion for Sameer, who is unaware of the storm brewing inside Naina. Later, Sameer finds himself inside the principal's cabin, where Naina finds herself in a spot of bother.

Naina is confused whether to reveal the truth – that Sameer beat up Pankaj – or stay quiet to save Sameer. Naina makes a choice and speaks the truth. Sameer is enraged at Naina but before he can do anything the principal informs him that his admission has been cancelled and asks him to walk out of the school. Has Sameer and Naina’s friendship ended before it had the chance to begin?

Naina is on cloud nine after receiving her new pair of shoes from Sameer, unaware that her crush is eager to exact revenge on her. While at school, Naina is eagerly waiting for Sameer. She gets ecstatic after seeing Sameer in her class. Naina is relieved that Sameer was not expelled from school. Sameer, unaware of the butterflies in Naina’s stomach, is scheming to steal Naina’s shoes.

When Naina comes to school wearing slippers, her classmates take the opportunity to get her punished. Naina removes her badge and after handing it to the teacher, goes out of the class to stand with her arms raised. Naina is comforted by her brother, Arjun. Later, Sameer remembers that he has kept Naina’s shoes in her father’s scooter’s boot space. While trying to hide the shoes from Naina, Sameer ends up giving it to her inadvertently.

Naina and Sameer are asked to deliver a speech about the ill-effects of smoking by the principal. Seeing the two together, the other girls in the school feel jealous of Naina. Later, Naina sees Sameer smoking on the roof. Sameer throws the cigarette bud in the air and it, by chance, falls inside the chemistry lab, resulting in a fire. Then, Naina is asked by the principal to reveal the name of the student who threw the cigarette bud in the lab. Will Naina reveal the truth this time too?

Sameer is unhappy that his mother has changed things around in his room without his consent. He shouts at his mother and leaves the room in anger. Meanwhile, Naina listens to a feature story on the radio and dreams of Sameer. Lost in her thoughts, Naina writes her and Sameer’s name on a sheet of a paper. The paper inadvertently threats to reveal Naina’s secrets before her family. Will Naina’s mistake cost her dearly?
