I’m looking for a manga (I think)

I’m looking for a manga about a child that I think was transported into a novel to be a child of nobility. But she was kidnapped along with her maid however the people involved were killed in a forest (I think the forest shows they’re long lost love) she was picked up by traveling merchants (possibly mercenaries) that had another boy in their party. They traveled across the land on Dino type animals that loved the kidnapped child. All the while her family was looking for her.
