Nachiappan eventually left the house along with Visu and Ramu to prevent Pechiappan and Sundarambal from separating over Meiyaththa's death. They both married for love in their youth, but Pechiappan's wife Sundarambal tortured and abused Nachiappan's pregnant wife Meiyaththa so badly that the latter died after giving birth to Visu and Ramu.

In a flashback, it is shown that Nachiappan had an identical twin brother Pechiappan, who lives in Karaikudi and is a simpleton. However, Nachiappan objects to the romance as he wants his sons to marry identical twin girls. Krishnaveny soon realises that Madhu and Visu are in love and extends the family's stay in the US.

Due to these actions, Madhu soon falls in love with Visu. The hospital compensates US$2 million to avoid a court case. He appeals aggressively to the doctors and has the error corrected by another surgery, then spearheads an angry fight for compensation. Visu soon realises that Krishnaveny is paralysed as she was operated on the wrong side of her brain due to a mix-up with another patient. Krishnaveny is admitted in the hospital where Visu works as a resident doctor and the surgery is performed. The twins arrange for the three to reach their host. After many confusions, the trio meets with Ramu also. Visu pitches in to help and learns that they just flew in from India so that Krishnaveny can undergo a surgery to remove her brain tumour. One evening, when Visu & Ramu go to the airport to do their lunch supply, Visu sees an Indian Tamil family from Chennai – Madhumitha 'Madhu', her younger brother Madhesh, and their grandmother Krishnaveny – having some problems with the immigration authorities.

They both are medical students and spend their evenings helping out their father alongside the restaurant's chief cook, Juno. He has two sons – Vishwanathan 'Visu' and Ramamoorthy 'Ramu' – who are identical twins. Nachiappan is a wealthy and successful Indian American restaurateur based in Los Angeles.
