I agree... I don't think either of them will turn negative 😆... Because first off there's never been a villian per se in DMG (thank God!) and secondly I think that this storyline has just been created as a 'pathway' to getting Muskaan & 'Rauul' together 😉...
So no I don't think either of them is negative or will 'turn' negative in future episodes...
Take Care!
Love, Hope & Best Wishes
