it's a historical drama
this lady is sitting on the floor in a palace being watched by a guy who is outside and it's raining
he comes in the palace dressed in white and he and her have a long conversation
she is upset because she thinks that he doesn't love her and that he is going to marry someone else
he lifts her up on to a desk or dresser and kisses her like she is his last meal and he is starving
he tells her that he will only love her and marry her something like that
I think he is in an arranged marriage to some minister's daughter or princess or someone like that
