Wow, honestly. I really love the concept already, and the art is super pretty too! As an artist I really struggle with backgrounds but I see you have no problem I am envious Anyway, plot-wise, it was very well explained from the outset, and the setting well-established. The characters seem very interesting too, I specifically like the girl with brown hair, though she emits tsundere vibes. Anyway, Great work! and keep it up!
