Like, shaan acknowledging that he finds her beautiful and that he finds her cute when she talks and that he is subconsciously aware and accepts the fact that he is her husband and she his wife.😉
And for Khanak that she too, as she had kept claiming to be his wife and was claiming her rights, subconciously, she too was beginning to accept the fact to herself too, and also that shaan is slowly starting to displace suraj in her heart and hence she let shaan touch her and in a way enjoyed it and also the next day her fear and prayer to god that she should never forget suraj and give his place to anyone else in her heart. ( which is already biginnning to happen I guess and hence scared her.😊)
