I don't think manish will re enter as bihaan. ..bcoz if he reenter as bihaan and if there is leap then obviously he will have to play role of old bihaan and father of young bani that jigyasa. .since he quit the show for not want to play old bihaan role I don't think he agree now. ..so I think Bihan is dead now...after 15 year leap bani will be with kosi and brainwashed by her. ..suhaan will be new character played by manish opposite baani (jigyasa)..so we will get to see our MANYASA Together again. ..
