Coincidentally, Chandru forgot to take that particular guitar with him. Sona also travels in the same flight and becomes closer to Chandru. Even though her intention was to get the diamond from Chandru, she starts loving Chandru. However she hesitates in conveying her love since she knows that her early death due to blood cancer is inevitable. The smuggler tortures her since the diamond was lost. Due to her circumstances, she is unable to keep her words and Chandru thinks that Sona is a cheat and fraud. Chandru's troupe returns to India. The smuggler feels pity for Sona and allows her to leave for India. Sona enters Chandru's house to Chandru's surprise. Chandru realizes that Sona is not a cheat and fraud. In spite of his mother's opposition and her terminal illness, Chandru marries Sona. Sona spends her remaining short life along with Chandru's troupe. Finally Sona passes away and Chandru decides to be a widower throughout his life.
A large portion of the film was shot in Singapore,[9] while additional scenes were shot at the AVM Garden Villa, Chennai.[10] The scene where Deepak (Rajinikanth) is challenged to flip his cigarette 10 times or lose a finger is based on Roald Dahl's Man from the South.[6]
The soundtrack was composed by M. S. Viswanathan while the Tamil lyrics were written by Kannadasan.[11] The disco song "Engeyum Eppothum" was remixed by Yogi BinPollathavan (2007).[12][13] The song "Sambo Siva Sambo" was remixed by Vijay Antony as "Avala Nambithan" for Salim (2014).[14]Sudha Ragunathan noted that "Ninaithale Inikkum just rocked the scene with MSV Sir bringing out his innovative streaks."[15]
Ninaithale Inikkum was released on 14 April 1979,[19] and Andamaina Anubhavam on 19 April.[20] Piousji of Sunday wrote, "despite heroic efforts by Kamalahasan to save the film, it disintegrates fast."[21] P. S. M. of Kalki appreciated performances of Rajinikanth and Kamal Haasan, Lokanath's cinematography and Balachander's direction felt Balachander made a film without a strong plot and called it just like that entertaining film.[22] Lokanath won Tamil Nadu State Film Award for Best Cinematographer.[citation needed]
The 2011 film Engaeyum Eppothum (2011) was named after the film's song.[23] In 2009, another film called Ninaithale Inikkum was released. Director G. N. R. Kumaravelan stated that the title was "right for my film on students and the college scenario".[24] The line "Jagame Thandhiram" in the song "Sambo Siva Sambo" inspired a 2021 film of the same name.[25]
Abaswaram Ramji conducted a stage show called Ninaithale Inikkum in 2006.[26] A play called Shiva Sambho named after the song "Sambho Siva Sambho" was conducted by Theatre of Maham. M. S. Viswanathan composed the background music for the play.[27][28]
