When a friend asks why Chaitu loves his first crush Suma, he says that his astrologer told him that he would marry the girl whose name starts with S letter. After this failed love story, he loves another girl in college whose name also starts with S, Sithara. The name of his third and final lover also starts with S, Sindhu. Although Chaitu was hinting the three on-screen ladies in his life, the real intention of makers seem to make audience correlate the S letter with Chaitu’s real life partner Samantha, whose name also starts with S.
To draw this analogy, makers cleverly selected the names of all three girls with S.
