It would be good on it's own, but it doesn't really fit the theme. These two were reincarnated, and neither was really a villainess to anyone for any reason. The original story may be that way, but in the end this doesn't really fit to me.
I guess I'm glad that this worked out, but if the two girls hadn't been okay with it this would've just been two girls getting their engagements annulled by two more fiances wanting to "follow their heart" and expecting the girls to go along with it.
