@Blossom - I think Manik has been explicit about his hate for Harshad, he has been very clear about his dislike but unlike the latter he is not obsessed with revenge. Alya also pointed out to Harshad how wrong he was. So something did happen which tore apart the friends . But I think it could be that Manik picked a side and Harshad felt betrayed, maybe fab5 castrated him apart and he holds the grudge of isolation . I don't know , he these days justifies his deed and actions to their hate which seems crazy.
@IS- Word. Manik for all his love for her has been very selfish with her. He expects her to behave and be with him all the time. He can push her but she should never leave his side. he demands her trust, her prayers and her light but what is he giving her in return?
I think this whole love story till this point has been about Nandini being the light in his darkness but now he has to work and be the firefly that keeps her going, making her smile and just shouldering her burden. This time he needs to listen and let her find demand from him.
@Rida - You are awesome👏
She made him chose and he knew it , feared it. Because he hates change, she turned his life upside-down , forced him to question his life principles and she is calling out on his BS, tearing his mask and bringing him to light. He is terrified of hope, love and happiness that she represents because thats what he always wanted but was denied.
