Mujhse Dosti Karoge?

Risha and Isha are identical twins. But their personalities are way beyond identical.
Risha is the perfect daughter anyone could want. She's got the brains as well as the beauty. Daddy's little girl, you could say.
Isha, on the other hand is the total opposite. She's the trouble magnet, a tomboy and nothing like her sister Risha.
The two of them just cannot stand each other and unfortunately, their parents make them share a room.
Will sharing a room bring them closer?
Why do they hate each other anyway?
