Boss Engira Baskaran

Chandrika rejects Boss because he attempted to copy during an invigilated exam, which she witnessed firsthand. This showed lack of academic integrity, and she disapproved of his behavior. Her initial negative impression sets the foundation for her prolonged resistance to his advances.

The exam incident where Boss tries to copy is the first interaction between them and establishes their contentious dynamic.

Boss leaves home because whenever he approaches Chandrika's family for marriage, his unemployment is repeatedly cited as a major objection. To prove he can stand on his own and be worthy of Chandrika, he decides to leave and establish himself financially.

Earlier, Boss's family mentions his unemployment as a barrier to the alliance, foreshadowing his decision to leave.

Despite Velpandi's threatening agreement, Boss persists with the tutorial centre. He appoints a blind teacher, which helps his son Paalpandi focus and start studying. The students eventually top the examinations in the state, and Paalpandi passes with favorable marks, turning the venture into a massive success.

Velpandi's backstory of exam manipulation hints at the twisted relationship with education that the protagonist must overcome.

Shanmugasundaram opposes their marriage as revenge for Boss failing to get a loan sanctioned. This personal grudge makes him act as a gatekeeper against their union, even after Boss proves himself successful.

The earlier loan refusal sets the stage for Shanmugasundaram's later opposition.

The fight between Shiva and Boss was entirely staged as a drama orchestrated by Nallathambi. Shiva is actually a teetotaller and the son of a businessman who is Shanmugasundaram's friend. The fake fight was meant to bring Shiva and Boss together and convince Shanmugasundaram to accept their relationship.

Nallathambi's tendency to plot schemes is established early in the film.

After Boss successfully runs the tutorial centre and transforms Paalpandi from a failing student into one who passes with good marks, Chandrika sees his determination and capability. The success of his business venture, combined with Velpandi's change of heart, convinces her to reciprocate his love.

The tutorial centre's gradual success mirrors Boss's personal growth throughout the film.

Velpandi tears up the agreement because his son Paalpandi passes the Class X examination with favorable marks, something no one expected. Impressed by Nallathambi and Boss's efforts in transforming his son, Velpandi not only tears the agreement but also offers Nallathambi a huge sum of money with no interest.

Velpandi's own history of exam manipulation creates irony in his son's transformation.

Nallathambi is Boss's only friend and owns a saloon. He acquired the saloon as dowry when he married a woman who was two months pregnant at the time of their marriage. This detail explains his financial situation and his willingness to help Boss succeed.

Boss chooses Class X students because Velpandi's son Paalpandi is in Class X, making this the key to his deal with the don. The agreement states that if Paalpandi fails, Nallathambi loses his property. By tutoring Class X students including Paalpandi, Boss creates a business that also resolves his dangerous obligation.

The deal with Velpandi directly ties the tutorial centre's focus to Class X students.

Paalpandi has a bizarre behavior where he sleeps in the examination hall, and if anyone tries to wake him, he bites their hand. This strange conduct is part of Velpandi's history of manipulating exams. Eventually, Boss's appointment of a blind teacher helps Paalpandi overcome this behavior and actually start studying.

Velpandi's own exam manipulation history explains Paalpandi's abnormal behavior.
