The chimera on Mars

Hello everyone, this is the first story I'm posting here and also the first English story I've written. Please be forgiving if it's not well written.
It probably won't be too long.
The story revolves around love and truth, freedom and conspiracy.
The setting is a city on Mars in the future.
Under the Mars migration plan initiated by people like Elon Musk, some humans migrated to and built a sky city on Mars. To adapt to the Mars environment, these people also underwent genetic modifications.
However, even in this new world, disparities between rich and poor and slavery still exist.
A small group of aristocrats with supposedly superior genes rule everything, while many chimera with animal traits and supposedly inferior genes can only serve the aristocrats as slaves. The aristocrats also indoctrinate them to prevent self-awareness.
The protagonist Alice is an ordinary girl. When she was very young, she was brought to serve the aristocrats and grew up alongside Duke's son Alan Blackswood. Despite their disparate statuses, the two fell in love. Alan is determined to marry Alice regardless of opposition.
However, after coming to Earth and meeting different people, especially boy Lucius, Alice gradually develops new perspectives and self-awareness.
Should she choose the Cinderella-like romantic love, or truth and freedom?
