Karthik believes in trying out multiple options before settling on the best one. This stems from his general life approach where he always wants the best of everything, from material possessions to experiences. He sees dating three women simultaneously as an experiment to determine which one would make the ideal wife, treating romance like a selection process rather than genuine relationship building.

Early in the film, Karthik is shown applying his 'try before settling' philosophy to everyday choices like buying pens and clothes.

Tejaswini's father Ranganathan, who wants to protect his daughter from heartbreak, uncovers Karthik's deception. He confronts Karthik about his lies and dual relationships. This revelation leads Tejaswini to dump Karthik when she confronts him about the truth.

Ranganathan is introduced as a caring father who is protective of his wealthy daughter.

After causing a traffic accident during his confrontation with Jyothi's brother Anbalazhagan, Karthik pretends to have lost his memory to gain sympathy from Priya. This calculated move is an attempt to get a second chance at love by exploiting her compassionate nature and belief in redemption.

Throughout the film, Karthik demonstrates willingness to manipulate others through lies to achieve his goals.

Karthik chooses Priya because her genuine love and sincerity make him realize the value of authentic relationships. After being rejected by Tejaswini and Jyothi, Priya's unwavering commitment and emotional depth help Karthik understand what true love means, leading him to abandon his manipulative experiment.

Priya is introduced as a girl with traditional values who believes in loving and marrying only once.

The accident occurs during a confrontation between Karthik and Jyothi's brother Anbalazhagan. After being beaten up by Anbalazhagan and his gang for betraying Jyothi, Karthik flees the scene in distress and causes a traffic accident, resulting in injuries that require hospitalization.

Anbalazhagan is introduced as Jyothi's protective brother who would react violently to any mistreatment of his sister.

Feeling betrayed and vengeful after being dumped by Karthik, Tejaswini deliberately befriends her rivals Jyothi and Priya. She gives them advice about quickening their marriage plans with the specific goal of exposing Karthik's deception and getting revenge for the heartbreak he caused her.

Tejaswini is established as a wealthy, confident woman who has emotional scars from a previous failed relationship.

At the film's conclusion, Karthik breaks the fourth wall to tell the audience he intends to become a new man who will only love Priya genuinely. He asks viewers if they believe him, leaving his reformation ambiguous. This narrative choice keeps with the film's playful tone while leaving audiences to question whether his transformation is sincere or just another manipulation.

The entire film has shown Karthik as someone who lies easily and manipulates situations to his advantage.

Ranganathan, as a protective father, cannot stand watching his daughter Tejaswini being deceived. Knowing Karthik's true character and his multiple relationships, Ranganathan confronts Karthik and reveals the truth to Tejaswini because he wants to spare his daughter from the heartbreak of discovering it on her own.

Ranganathan is introduced as a caring father who is concerned about Tejaswini's wellbeing given her history of failed relationships.

Jyothi, who is fiercely independent and has a strong sense of dignity, cannot accept being deceived in a romantic relationship. When Tejaswini reveals Karthik's scheme of dating all three women simultaneously, Jyothi chooses to reject him rather than continue being part of his manipulation, demonstrating her self-respect and integrity.

Earlier, Jyothi is shown slapping a man for inappropriate behavior, establishing her strong boundaries and self-worth.

Karthik learns that genuine love cannot be found through deception and experimentation. His journey from treating relationships as a game to eventually appreciating sincerity shows his character growth. However, the ambiguous ending leaves viewers questioning whether he has truly changed or if his promises are just another form of manipulation.

The film establishes early on that Karthik's approach to relationships is flawed and based on superficial criteria.
