Abhay does not plan to make Piya fall in love with him. Heck no. But Piya attacked his ego today and knowing Abhay , he always gets caught between his head and his heart. Psychologically , he is conditioned to hate and distance Piya but emotionally , he cannot stop reacting to her.
Abhay-T are a result of the conflicting complication between Abhay's mind and heart. And this is what makes him vulnerable and sends alarm bells ringing for Haseena and her Chand.
