The 25-year-old actress will essay the role of a Tamilian girl Mahalaxmi in the show, which is story of two people from different castes who fall in love.
"Love is sufficient for two people to be together and not the similarities or dissimilarities of caste, religion, creed, which are man-made.
"The kind of love story 'Yeh Hai Aashiqui' has come up with this time, is brilliant and very real as we know that there have always been issues in our country, specially relating to inter-caste marriages," Sara said in a statement.
