Out of the scenes you've put in the poll it's hard to choose between the Rishbala dance and the shirt changing scene.
The dance, it started off fast and RK manoeuvring MB around quickly, then as Madhu met each move with her fighting spirit and never breaking eye contact, RK was jarred at her her stubborn spirit and he slowed the dance down, possibly he liked how she felt when she was close in his arms or because he wanted to read more of what her eyes were telling him as she met him move for move, I really liked the slow part when they were facing each other and whenever she twists away to twirl he brought her back to his chest (close) so for me of the scenes you chose I like that one best. But a close 2nd is the dressing him up in the shirt scene as again the eye contact reading into each others eyes was there, and when she shrugged out of his half arm embrace you can tell he wanted her to finish putting the arm brace on and settle him properly so he didn't like that she left him despite her excuse of the puja preparations, and he followed her with his eyes when she moved and even quickened her step to a run to leave the room, as he turned to look she had gone...so she left his heart a little bit unsatisfied, so now this scene of the room arrest and his excuse to Bittuji is also partly because of what happened before, yes he wants her to change out of Deepali's saree, possibly he gifted the saree to Deepali and knows Dips is upto something nasty on his wife, he is keeping her in the room to safeguard her from Dip's plans, but he also likes being in her company just the two of them, she fascinates and entertains him. So his happy there in the room just the two of them.
