Somewhere along the way, the duo falls in love, throwing some soft glances at each other when the other is not looking. Their college mate Karna (Yugendran), makes devious plans to separate the duo and make Chella his. He does not seem to have any running feud with Chinna, is quite friendly with the duo, and does not seem to be particularly in love with Chella. Chinna laps up all that Karna tells him about Chella loving him, and is heartbroken and goes out on a business trip. Chella, persuaded by both families to marry an NRI, boldly informs them that she loved Chinna and would marry him. The two families are happy. Chinna returns home and learns of the preparation for his engagement ceremony. Feeling that since Chella loved Karna, it must be family pressure that must have forced her to agree. Chinna then backs out. It is Chella’s turn to be indignant about Chinna’s mistrust of her love, and after giving him a piece of her mind, she backs out, with Chinna pleading for acceptance. After a period of separation, during which all ties between the two families are severed, Chella’s family soon come to realise that they cannot live without their dearest friends (and lover).
