Harsh..... Reincarnation of Devi laxmi. Went to Dwaparyug, suffered and cried. When it was the choice between love and self respect she chose the latter one... Krishna..... The supreme lord but a loyal lover to his Laxmi. He was always there for Harsh. He laughed with her, cried with her and finally cried for her. When his Harsh chose to leave.... He chose to follow..... Yup! He is Krishna and yup! He is kalki too.... Detailed description is inside the book.... Because I really suck in giving descriptions. It is the part 2 of Unknown Destiny - The Mahabharat Fanfic ... I suggest to read the first part of book so that you will understand what is exactly going in this book
