I said it in a previous thread but I think she fell for Gran at the end of her 5* Fate when he saved her from her suicide. There's also her fifth Valentine's seasonal where she says she's not against being (you)r lover if you want her, only to tell herself to stop fantasizing afterwards.
I guess what im saying is that they've been slowly building up the idea of Haase realizing she wants danchou over time, and it isn't until the summer fate when she actually acts on it. Even outside of my massive Haase bias, her being for (you) feels pretty natural and nice.
