I can't tell you how satisfying this was to read omg.
LOVE how you included Aditya in here, observing all the goings-on and FINALLY realizing he's gonna be the third-wheel in every Shravan/Sumo interaction. I was inwardly yelling "YAS" throughout this whole thing because I loved every bit of it. There was so much intensity and passion and yet light-hearted moments too and everything just flowed together so beautifully <3 I can't get enough of flirty/besharam Shravan and you always describe that side of him so well! That haldi scene was something else, gonna just fan myself from all that heat, phew! Love how he left his handprint - it's like he left a mark of his own to claim her as his - damn, how I wish this had really occurred instead of Aditya being the one to put haldi on her. I also really liked the return of some of that childish action, the two times it's occurred in the show, I get the biggest smile on my face and the same thing happened while I was reading the scene in your one-shot.
I think what I enjoyed the most was that Shravan took ACTION. He didn't just sit around and avoid confronting his problems/making assumptions. He observed, like the good lil Oxford graduate he is and made astute conclusions over Sumo's attraction towards him and he decided to DO SOMETHING about her reticence - he brought out her innate passion/emotions which she's been trying to keep at bay and by doing so, pushing her further to revealing the truth.
Amazing job with this one! <3
