Make it thrill... It's not ghost story, it's worst story.
Even After hearing this, kindly change the flow.
Let swetha marry mutharasu and let him realise the fact, kill that stupid character. End the story.
THE END
or
Make mutharasu character atleast little brainy, let him investigate all the truth with the help of venilla, parallely let make swetha continue conspiracy.
Swetha character is fine
