They are caring and loving to him, while having a daughter, who is like a sister to Mani. Mani's brother-in-law wants to get their daughter married to Mani. But Mani happens to have learned that his cousin is in love with some other guy, who is jobless like him and cancels the wedding plans paving way for his cousin's wedding with her lover.
