NIIIIIIIIIIIIIIIIIIIIICEEEEEEEEEEEEEE
I see, I see how it is, the Princess girl got her freedom or something taken in the past and now she's overcompensating for it by being extra determined and hardworking (though it seems she is naturally talented as well) to manifest her own will and is very prideful.
But now enter the Gloomy girl, who is her opposite and does whatever she's asked of, and has extremely low self-worth.
Marie is upset that someone forced her to do something, for sure, but the main conflict for her is that she hates what Aki does to herself, since she sees her old self within her, well, that is my early conjecture anyway, it seems there is also someone in the background, perhaps still controling/obsessed with Marie and badly enough, ryona

That being said, ... this doesn't explain why Aki's kiss was so passionate though
, an amazing new spicy yuri manga indeed
