just the way purab was committed to aliya but fell in love with bb the same will happen wth tannu-abhi-pragya!! indeed its more serious in abhi's case cause purab only made a promise but abhi was committed to tanu indeed they were quite close. So i guess when the same thing will happen with abhi as purab said ''ussei sachayie pata chalegi''.
and as we can guess tanu wil turn aliya i mean vamp 😆
