Listen! If you are going to rescue your princess and then be wed, it’s all about presentation. Do it right and get something like this Legend of Zelda Ring Bearer Pillow. She will be glad you did and she will say yes faster than you can button mash.
Of course if it is anything like these classic games, she will just get herself in trouble again and you will have to rescue her all over again. But until that happens, you can get this beautiful pillow from Etsy seller Red Panda Gifts for $45(USD).
Not sure what that works out to in rupees though.
