Mr. Housekeeping

Isai ends their relationship on the last day of college after realizing Honest's chauvinistic attitude. Honest challenges that he will win another girl's heart and prove Isai wrong, setting up the central conflict. The breakup marks the film's beginning and motivates Honest's later attempts to rebuild his life.

Four years later, Honest is jobless and desperate to earn money to pay off a sextortion threat. He takes a housekeeping job at a villa, unaware it belongs to his former lover, Isai. The job forces him into close contact with her, setting up the intertwined fates.

Isai's maid, Jothi, tests Honest's skills as a housekeeper to gauge his potential. He fails the initial assessment, but Isai still decides to hire him for the villa. The hiring marks a surprising reconciliation of sorts between them.

Honest uses his advance payment from Isai to settle the sextortion debt everyone knows little about. He then deceives his family by claiming he has landed a job at an IT company. The deception foreshadows later complications when his true work life collides with his family's expectations.

Honest accidentally becomes part of Isai's official meeting, triggering embarrassment for her and their college friends. Isai publicly exposes his supposed job, revealing that he is her househelp. She slaps him in public, though she soon regrets the moment.

Honest's family is on their way to meet Priya when their autorickshaw runs out of fuel. Isai offers them a ride to Priya's house, and Honest develops feelings for Priya. She relieves him of his househelp duties to help him secure a better job, though he continues working for her until the marriage is settled.

Isai and Honest's family bond deepens, and she learns that he secretly provided her with food during her last college semester. She sees his genuine care and accepts him as her best friend. She even hints she might love someone, which Honest misreads as a romantic confession.

Isai's ambiguous confession leads Honest to believe she approved a romance, prompting him to call off his engagement to Priya. Around this time, Isai starts dating her colleague Harish and gradually falls in love with him. Aware of Honest's feelings, Harish advises keeping distance.

Isai mentors Honest and helps him land a job at her company, deepening their professional but complicated bond. Harish grows jealous and warns Isai about a potential possessive suitor. Honest takes this as a sign of his own acceptance.

Isai invites Honest to her home, leading him to believe she is ready to accept him romantically. Instead, she confirms they are just friends, leaving Honest heartbroken. He attempts to jump into the ocean but is saved by Roman.

Heartbroken but determined, Honest tries to pursue Isai despite her rejection. Harish and his friends assault him, and Honest fights back with his own gang. At the police station, Isai intervenes and refuses to file a complaint, citing pity as her reason.

Honest's parents worry for him, and his sister Sangeetha helps him realize he should have respected Isai's boundaries. He gradually distances himself from Isai to avoid repeating the hurt. The realization marks a turning point in his personal growth.

Isai uncovers Harish's live-in relationship with Deepthi and has an argument with him. She begins to see that Honest truly loves her and questions how she misjudged his intentions. This shifts her feelings toward Honest.

Six months pass and Honest operates a housekeeping agency in Chennai with his friends, building a life after the turmoil. Isai decides to take a chance and proposes to him, deciding to unite with his love. They finally come together.
