Manga Of course, I'll claim Palimony!

My fiance suddenly announces that he is breaking off his engagement with me and will now live with another. Pretty quickly I understand that he is in love with a girl who has recently appeared with us and is the daughter of the count! Now he will try to do his best to make me a villain, which will allow him to legally break off the engagement. However, can I demand a huge fee and leave peacefully? How do you like this proposal?
