On the first day of 9th standard, Samvidhan Sharma, the eternal sidekick finally gets a chance to speak to his crush and the school’s prettiest girl Jasmine. But things take a turn for the worse, when Jasmine’s best friend and sidekick Aadhya, accuses him of cheating.

After a complaint to their strict school principal, Samvidhan and Prateek are not allowed to perform their rap on the Founder’s Day of Lucknow Central Convent school. Samvidhan assumes that Aadhya has made the complaint and has a huge showdown with her. But this misunderstanding leads to an unexpected friendship. Could this be the start of a new romance between the two sidekicks?

Aadhya and Sam form an organic connection and discover they have a lot in common. The once-enemies now talk all day on their phones and through hidden messages left in their favourite book in the school library for each other. When they team up for a flying model competition, their chemistry only gets stronger. But does Aadhya have the same feelings about Sam, or is he just another friend?

Sam realises that he is in love for the first time and decides to propose to her. As Aadhya's strict mother Vandita joins school as a substitute teacher, bad timing and luck continue to be his fatal foes. As a worried Aadhya distances herself from Sam, and misunderstandings follow, Sam becomes anxious about Aadhya's blossoming friendship with Sahil, the most popular senior and aspiring poet.

Students and teachers alike, including Sam and Aadhya, are prepping for their Valentine's Day dates at Lucknow Central Convent. However, Aadhya's father's sudden visit on February 14th throws Sam and Aadhya's preparations into chaos. Will Aadhya be able to make it to Sam's romantic night packed of surprises, or will another surprise catch them off guard and them to question their relationship?

When Sahil, the most popular senior in school, becomes a huge bone of contention between Sam and Aadhya, Sam decides to break up with Aadhya, leaving her completely shocked and confused. All this right in the middle of their final exams. Will Sam ever be able to get over his insecurities and stop comparing his sidekick self to Sahil or will he let go of his first love?

As the school reopens after summer vacations, Aadhya is confronted with some harsh realities, and Sahil is appointed as the leader of the delegation to represent LCC at Celesta Interschool Cultural Festival that is to be hosted by current champions and archrivals Francis Convent School. While Aadhya tries to cope and deal with the shock, something is brewing to heal her. But will that be enough?

In their first interaction, Aadhya declines the help offered by Samarth. On the other hand, while Prateek's and Zoya's differences come out into the open as Sahil begins auditioning for Celesta, Jaz finds an opportunity to get closer to Sahil. As the team brainstorms on the topic for Triveni, the main event of Celesta, Aadhya recognises a friend in Samarth.

While Sahil struggles to assert control over his indisciplined team and finds a friend in Jaz who motivates him, Aadhya faces embarrassment at school due to a personal message getting leaked, which she blames Samarth for. Feeling dejected by him, she finds a friend in her mother who helps her understand things in context while Samarth gets into his first school fight.

Aadhya reaches out and mends things with Samarth. Sahil gets a hint of how Jaz feels about him and Prateek learns his lesson as Jaz and Zoya indulge in a catfight as they audition for debate team on the topic of love. While Prateek and Zoya patch up and Aadhya and Sahil engage in a bitter argument, Father Lawrence announces a mandatory test for all team members to retain their place in the team.

As the practise sessions extend beyond school hours, Zoya encourages Jaz to express her feelings for Sahil. Samarth makes Aadhya sneak out of school and surprises her only to be surprised himself. The LCC team suffers a last minute setback as they lose a topic to Francis Convent due to late submission.

Team LCC manages to find a topic after a last-minute setback but finds itself on slippery ground as the cracks within the team widen and they lag behind on the points table.While Sahil finds a way to keep the team united and competitive, Samarth realises the stakes on his shoulders for the team's victory.The competition closes with a surprise as our characters are confronted with revelations.

With the board exams concluding, Father Lawrence offers the students of standards 11 and 12 to use their summer holidays for an exciting summer exchange programme- Young Tarang, at Don Roberts School, Dehradun, which brings a smile to Aadhya's face, and she gets on to the task of persuading Zoya and Jaz, who are unsure about the trip.

Aadhya and Samarth reunite after manoeuvring through months of long-distance relationship, and are set to finally spend some quality time with each other as others forge some new associations at summer camp.

Samarth tries to plan the best birthday for Aadhya, full of surprises. However, little does he know that while his best efforts seem to fall flat, he'll eventually be left shocked himself.

As Samarth tries hard to recover from the shock, his equation with Aadhya continues to go downhill. While Aadhya tries her best to make the most of her time with Samarth by managing to get him inducted as a volunteer in Young Tarang, others in the group also struggle with their insecurities as new associations take over the existing bonds.

As the camp enters its final leg, on one hand, Aadhya and Samarth contemplate the future of their relationship, while on the other hand, some friends patch up to set out on a new adventure. However, things get worse when a few misadventures damage LCC's reputation, and they find themselves on the verge of a premature exit from the camp.

The LCC gang survives the storm with some interference from their faculties and manages to conclude the summer camp successfully. However, as they are set to return to Lucknow, while some new friendships come to a sweet end, Aadhya and Samarth meet to discuss the future of their relationship. But little does Aadhya know that just when she feels that her life is driven by her decisions.

As our gang steps into class 11th, not everyone is happy with their board exam results. Jaz has fallen to Aadhya in terms of a rank in school while Prateek has flunked one of the easiest subjects ever. While the other two in the Todu Teen sense something’s up with Aadhya, she doesn’t speak up. Whatever transpired between her and Samvidhaan in Dehradun is unknown to the others.

Samvidhaan’s return to LCC is nowhere close to a hero’s welcome and he realizes that he’ll have to win everyone over to cement his place as the likeable sidekick at LCC. Meanwhile, there are misunderstandings between Todu Teen over multiple rumours, one of Prateek flunking EVS, and the other of Aadhya leaving Samarth because of Samvidhaan.

It’s friendship day, ironically for our gang which has just broken up. Samvidhaan knows that before wooing back Aadhya, he has to win his best friend back which doesn’t seem to be an easy task. Meanwhile, as a new fad, there is a set of different colour friendship bands that seem to be floating around the school. The catch being every colour has a different meaning.

In the quest of winning Aadhya back, Sam and Prateek have a hilarious idea to get the Todu Teen together. However, the idea backfires but it does help Sam in unknowing ways. Meanwhile, Rajat gets a reality check from his friends on the ‘jealousy’ thing with Jaz.

With the Todu teen back in the previous episode, it’s time for the two of them to help Sam find his way back to Aadhya. Meanwhile, Sahil finds it hard to concentrate on his upcoming pre-board exams.

After the Kachehari, Sam and Aadhya are together again, but the atmosphere of farewell and goodbyes makes them uncertain about the future and they’ll have to take a solid step to cement their relationship.
