first of all *THIS IS MY OPINION* but i think the story would kinda suck. personally im not a অনুরাগী of জ্যায়াই so thats why. i would never see them as a couple so i dont get how the story would work. so জ্যায়াই fangirls dont get all mad. this is my honest opinion. u guys can say wut u want and i can say what i do
