Acha so u didnt see earlier epis I guess he did many more things then wat u have mentioned now that his character is going that way thats y he is acting like this
And wat TK know just to give wierd expression n to blush n see dreams of him n kittu being together though he knows that Kittu dont love him😡
as far as i know... kittu herself told her dad that she loves yuvraj but doesnt know how to tell him (the day uv proposed her)
