Actor Sayani Gupta does not really believe in the institution of marriage.

"I have a different idea of companionship... I used to believe in the institution of marriage.. it works for certain people and does not work for some. I feel marriage is not really necessary for one`s happiness. You really don`t need a man to live happily ever after. You can live with your friends.. you can live with your siblings... you can live alone and enjoy your own company. It really depends upon person to person. Maybe after five years, I will be saying something else because it`s an evolving thought," Sayani told ANI.
