well i think mayank will be caring but will find it hard to express his love it on a daily basis but with nupur in his life we will c him opening up abit .one thing is for sure he will be very possesive in loveeee.after seeing him the way he reacted when cheeru je was there n when nupur opened up her hair n the way he was protecting her from boys eyes😆..as far as nupur is concern she will express her love in every way she can.flowers, ghumna phirna masti n making mayank do masti too but making him focus on his goals too n mostly she will take lots of care of his mom too same is for mayank ..he will b a concerned n a caring bhai for gunjan too😛
