He’s super kind to her, but in the end, he’s only that way because he believed she was a Bonuaparte. The moment his sister tells him she isn’t, he drops her and treats her like she’s not even worth being polite to. FL then realizes that she ignores the signs of his true personality throughout their relationship, because he’s always treated commoners and people of lower status like they don’t even exist or like they shouldn’t even try to be or speak around him.
Loving the grand-ma already. I wonder when the FL will fall for him though. According to spoilers…
***SPOILER***
She’ll eventually admit she has feelings for him but still refuses to act on them so she goes through with being with Lucrezia’s brother.
