Romance. Starts with 2 sisters, Delicate and Tomboy, Delicate dies in a stupid way when they were being pursued

I think I read this book around 2018 but the book was older than that.

I don't remember if the sisters are twins or just sisters. I'm going to call them Delicate and Tomboy (she isn't really but isn't lady like enough).

The sisters are in trouble and at least one of them needs to marry so they can solve problems. I think their father just died or is in his death bed and they are about to lose their home? Delicate got an engagement offer and had to travel in other to meet the guy and officiate things, but was very distressed/nervous/scared, so the Tomboy went along with her dressed as man pretending to be her brother/cousin to protect her. The servants thought their relationship very suspicious and potentially incestuous, because the girls at times forgot Tomboy was supposed to be a man. Stuff happened and more stuff happened the sisters are pursued for reasons. I think they were trying to kidnap Delicate? Anyway, Delicate dies in a stupid way. I think she feel from the horse? Or she slipped and hit her head when she fell? It was instant death whatever the case and I remember I got really mad about that. It was very unnecessary. Tomboy was kidnaped instead of her sister by some crazy guy who had issues with Delicate's fiancee and wanted revenge. Tomboy gets rescued by the male lead who was NOT Delicate's fiancee. Delicate's fiancee finds out about the whole crazy guy ploy and Delicate's death and is devasted about it all but deals with the rest of the situation. Tomboy marries the male lead and I think names her daughter after Delicate? I also remember I didn't really like this book but really want to remember it anyway lol
