I dont think the marriage is anywhere on Kesar's mind or even Gulaal's in a way, its only when certain ppl make remark to it, she gets prick that yep they are married and so on, and like you say i do think she is aware that there seems to be an growing attraction with Kesar towards her and so on, and maybe her being more aware of him reflected in that scene and also asked herself what does he want and esp as he grabbed hold of her and pulled her close, well he did to himself go close to her
