Because of this, he starts to wait in the subway every day. Subiksha does not come, but on the other hand, she visits his workplace in and his friend's room, where he stays. Unfortunately, both times, he does not make it in time to meet her. Finally, when he meets her, she tells him that they have already met at a party where their mutual friend asks her to drop him at his place as he is very drunk. This happens on her birthday. However, Vinod does not remember this incident.

When Vinod replies to Subiksha's proposal, she rejects him by stating that she just messed with him for his behavior on the night when she dropped him at home, though he continues to pursue her. Subiksha puts a condition that if Vinod fought with Ashwin Ranjith, a boxing champion, she would return his love. Vinod then practices boxing to fight Ashwin. Although he loses in all of the matches he had participated, he learns how to punch and block punches. He plans that in front of Ashwin so he will not fail. He goes to Ashwin's place and fights with him. He records the fight in his phone to show Subiksha the fight. After the fight, Vinod takes Ashwin's silver medal and tells him to take it soon after defeating him. Subiksha calls Vinod and tells him to not hit Ashwin, but when he tells her that he already did it and recorded the fight, she gets happy. One day, in a coffee shop where Vinod was, a girl accidentally pushes him, and his phone gets broken. Subiksha comes there and asks Vinod to show the video. But when he tells her that his phone got broken and he could not watch the video, she thinks that he lied to her and leaves. Vinod takes his phone to a mobile shop, and the owner tells him to come tomorrow to check it. But he uploads the video on YouTube, and everyone including Ashwin sees it. His master tells him that it is a punishment that he got for betraying everyone for money.

Subiksha sees the video and tells Vinod the reason why she told him to beat Ashwin. He reveals that it was not for her but for him because of an incident that happened because of Ashwin. In a flashback, it is revealed that Vinod loved his father dearly and was at a shopping mall happily spending time with his family, but Ashwin unknowingly sits on some hot dogs. Because of this, Ashwin publicly hits both Raghuraman and Vinod and tells Raghuraman to rub off the hot dog cream. Raghuraman rubs it with his shirt, and they gets insulted in front of the people who saw the incident. After this incident, Vinod stays away from Raghuraman. Raghuraman, who is Subiksha's colleague, narrates this incident to her, which causes Vinod to defeat Ashwin in the end. She even reveals that she knew that Vinod is Raghuraman's son on the day of the party when she drop him to his friend's house when she checked his purse and saw his family photo.

Meanwhile, in a press meet for Ashwin where everyone tells about fight video, Raghuraman arrives there soon after watching the video and calling Vinod to the place. When he tells that his son will come to fight with him, Ashwin tells him to bring Vinod to the place, and he is ready to fight with him in front of the press. Soon after Vinod arrives at the place with Subiksha, he asks him did he beat Ashwin and he tells yes. Raghuraman tells him to go and fight with him in front of everyone. That time Subiksha tells Raghuraman that she loves Vinod, to which he gets happy. He calls Vinod's mother Selvi and tells her to on the TV news where she saw Vinod and she gets happy. During the fight, Vinod gets beaten up by Ashwin at first. But when Vinod hits Raghuraman back, he removes his T-shirt, showing his muscles, and hits Vinod again. Vinod then pulls his shirt, showing his muscles, and fights him back and at last wins. Selvi tearfully smiles after seeing this. Vinod asks the press that if he beat him is wrong to forgive him and he fought with Ashwin as he thought that Vinod doesn't know fight on the incident that happened to him and his father. Then he leaves the place with his father and Subiksha.
