Arun, a teenager from Kerala, enrolls in KCG Tech in Chennai and instantly notices Darshana, sparking a first attraction. They begin a relationship and navigate the typical college romance while balancing studies and dreams. This marks the beginning of Arun's dramatic personal journey.

Arun accompanies his friend Antony to meet his online girlfriend and feels drawn to the colleague instead. He lies that he is single and leans in for a kiss, but the moment is interrupted by the moral police. The incident strains Arun's relationship with Darshana from the start.

Arun admits the lie to Darshana, who is livid and ends their relationship. The breakup casts a long shadow over Arun and pushes him toward a troubled phase. He starts to question his choices and his future with her.

With the breakup, Arun descends into ragging juniors and heavy drinking. He enters a new relationship with Maya, but the happiness proves fleeting and hollow. His self-destructive habits alienate friends and family alike.

Darshana begins dating Kedar, a charming but deceptive figure. She eventually breaks up with him after discovering truths about his identity. The two drift apart as Arun watches from a distance.

Arun's father notices his decline and urges him to quit alcohol and start anew. He and Antony join Selva's coaching classes to salvage their academics, giving Arun a fresh sense of purpose. Darshana begins to see a changed side of him as well.

Selva dies in a bus accident, sending shockwaves through the group. Maya ends her relationship with Arun after her father's death, realizing he may not truly love her. The losses push Arun to rethink his priorities.

On the final day, students are led to a room called the 'secret alley' to leave messages for the next batch. Arun finds himself unable to write anything meaningful, signaling uncertainty about his future. Darshana accompanies him to the train and questions whether they would have stayed together if not for the past argument.

After graduation, Arun lands a job during a campus interview, starting a new phase in his life. The initial success does not fully erase his lingering doubts about happiness and purpose. He begins to chart a different path, unknowingly setting the stage for future changes.

Two years pass and Arun feels dissatisfied with his corporate life, leading him to quit. Darshana, now a YouTube vlogger, encourages him to follow his dreams. On a bus journey, he meets Jimmy, a wedding photographer, and they form a company specializing in intimate weddings.

The company receives a shoutout from Prateek Tiwari, a batchmate who has become a Bollywood singer, bringing in a flood of bookings. Arun's confidence grows as the business gains traction. He finds purpose in creating memories through photography.

During a wedding assignment, Arun spots Nithya Balagopal and is drawn to her. Impressed by his work, she recommends him to her cousin on the brink of marriage. When he discovers the groom is Kedar, he exposes his deception and saves the cousin from a disastrous match.

Arun and Nithya's wedding is celebrated with family blessings, and Darshana attends the reception but cannot bear to see him with someone else, walking away in tears. The union marks a new chapter for Arun as he begins a life built around his growing family.

Nithya gives birth to their baby boy, a moment of pure joy for Arun. He tells Darshana the news and, in a gesture of remembrance, names the child after their late friend Selva. The name links his past to the present.

Darshana's marriage is finally fixed, and Arun and Nithya accompany her to her home for the engagement. That night, she calls him to meet at the beach where their feelings once resurfaced; he contemplates but supports his new life with Nithya. Later, at KC Tech in Chennai, Arun retrieves the secret alley key and leaves the campus, grateful for the journey they all shared.
