Why he threw her out of house? Or KT told him as in last precap he said he has to do something indirectly.
KT is trying to help her from every possible way. His mom said to bring back Preeti asap in the house but he said he want to take things slowly so that it dont feel like he is pressurizing Preeti. So seeing she in need for money for Jr Preeti's admission he organises a Golgappa eating competition where the prize money is 35,000 rupees. Its a fixed competition where all the participants are paid except Preeti whom he wants to win. He cannot go and directly help her with the money thats why he does it. What happened in the precap is maybe Vishal lost the competition from Mohi (Preeti) and in anger threw her out because he thinks because of Mohi he cannot come as a good father infront his daughter. That will be revealed in monday's epi.
