Manathodu Mazhaikalam is a 2006 Indian Tamil-language buddy drama film directed by Arputhan.
The film stars Shaam and Nithya Das as college mates and good friends who maintain their platonic relationship despite their parents' misconceptions about their friendship. The story follows the lives of Siva (Shaam) and Sathya (Nithya Das), who get married to Sruthi (Sameksha) and Karthik (Jayasurya), respectively, but face personal tragedies that test their friendships.
The film ends with a poignant note as both Siva and Karthik, now widowers, vow to remain good friends for the remainder of their lives.
