I felt Ramans Ice yesterday

Yesterday, when Raman was talking to Mani 'don't you think your asking the wrong question' I could really feel the ice in his voice, and it felt like his cold buisness man avatar was back on which freaked me out for a moment because I hadn't seen it for a while since Ishita came and their relationship was built. It feels like he trying to become solid ice like he was before Ishita thawed his heart, now he's trying to revert himself back into the buisness Man he was before, since then I've been thinking of him as more of a family man now, I know it will affect Ishita only, but I am just worried that his behaviour will have affect on the rest of the Bhallas as well.
I know that Raman is good inside and is just showing a rough exterior to mani because he hates him for obvious reasons, but this will also affect Ishita because Raman was really pouring ice cold water every time he spoke to her today.
