AnimeOTK - A Magical Winter

In an 1800s-type setting, it's wintertime, and two orphaned kids of rich people, about twelve or thirteen, live in a mansion with two sickly children (the same age or younger) who used to be their servants. With their parents gone and uncaring relatives messing with their money and lives, they all struggle to survive together on their own, but find comfort in eachother. Could introduce fairies or magical elements if you like. I want to play at least one top and one bottom character. My RP partner would have to be ok with at least two gender pairings, and at least one would need to be male-dominant. Thanks! :)
