Goutham then discovers his father was ill and rushes him to the hospital, where the doctors say his father is suffering from pancreatic cancer and cannot be treated. Goutham becomes heartbroken. Sri comes to meet him and tells him he knew Sridhar was suffering from this disease. Baby then comes and says Sridhar was the one who compelled them to get married so Goutham might change his mind and get married. As the three friends reconcile, Priya comes to the hospital to meet Sridhar, where Gautham apologizes and admits to Priya he has fallen for her.
