However my heart went out to kunj in the first part of the episode when twinkle re-entered the house, there were tears glistening in his eyes and a glow on his face when he saw twinkle that moment and he was unable to take his eyes off of her during that entire scene especially when twinkle walked past him and looked at him then she herself was the one to look away from him and walk away from there, but he kept his eyes locked on her even then, including a faint smile on his face and tears in his eyes. He was truly so happy and relieved to see her in the house again, but kept his actual feelings hidden due to his own ego and anger.
You could also tell he was disheartened knowing twinkle had decided not to come back in their bedroom and instead stay in the guest room. He hasn't been sleeping properly since she left and has been staring at the empty bed non-stop at night missing her presence so the idea of her being in the house but not in the same bedroom is something he is not accustomed to and it disturbs him knowing how big the differences between them have gotten, but he wants to supress the pain that her being away from him gives him. I think secretly he is happy and at peace with the fact she is back in the house and in front of his eyes almost all the time now apart from at night.
