Wow! That was a really emotionally charged chapter!
Khushi in blind to everything else except having Arnav in her life, at any cost. You have done an awesome job of explaining the metamorphosis of her feeling for Arnav with her age and time, the gradual maturation of her feelings at the same time have her efforts to exorcise herself of the same..
Arnav is more mature than hot headed in this fanfic. Though the last para is contradictory in itself, it leaves lot of room for speculation. Also, since you have stated that this is NOT a dark fanfic, I am holding you to your promise to surprise us .
The act of spooning has more friendly and comforting overtones than sexual.. We should not forget that her act of disappearing has rattled Arnav, he now knows how firm is her resolve, she will not give up easily on him. He has seen how she while conceding with his wishes twists his own words and uses them against him. He has seen an example of this in NK;s case. There was also a time gap after which he arrived at her room. He must have formulated some kind of plan. This was the same ASR who instead of buying Khushi from Shyam, induced him in the game of cards and cunningly left him with no money. He has protected and cherished her for so long, it goes against his inherent nature to let her give away something so precious..
I think instead of pushing her away, to which she does not respond very well, he will state that he is willing to give this relationship a try. He may ask her to work at his office, so that they can spend more time with each other, it also added experience to her resume which can be useful for her if she wishes to pursue her education later. He may deduce that since Khushi has not knows many men other than him, her will she to it that she comes across young dynamic men while working at his office, the work and new environment may change her mind to new choices. He will subtly try to nudge her in their direction. He may ask her that since he is willing to give their new relationship a try, he has not seen her quite in that light and he needs time to come to terms with that and she owes that to him. Also to keep their new status under wraps from prying eyes especially nani's.
At the same time a new distinguished professional man may make an entry. Arnav for now is ok with Khushi transferring her affections to some other man, but the place of honor, that pedestal was reserved for him only. Will he be able to handle Khushi looking with awe and respect towards this man.. He may start to fall for her during her stint in his office, when he realises no matter how wrong it may seem to him or society, her feeling run too deep and it is not just a phase for her. The other man may be aware that Khushi has an ocean of love in her eyes for someone else. He may guide her to get what she wants but at the same time be mature, compassionate, to understand her beloved needs, to wait for him. Khushi's emotions are all over the place and she very much needs a steady hand and a kind shoulder to lean on..
That is just my POV. I am really interested to know what turn this fanfic will take, how you are going to stage revelation of Arnav's past. Will it be mother father conflict, spurned in love, unrequited love, physical short comings like he takes women out and let other draw what conclusion they want from it, he fears that he carries genes of his unscrupulous grandfather, he loves Khushi but feels he does not deserve her because of her past, work is my baby and no one comes between us, some promise he made someone...
Thank you for this great ff. Hope you will feel better in time.. Usually stepping out, reading a great book, chatting with friends, going for a small trip helps me feel better. If is time in general that as they say - "this too shall pass.."
