Being a princess is not easy. All these duties, training with royal knights, meetings... But Selena only enjoys them, because she is sure that one day she will take the throne and become an ideal ruler. But one unfortunate day, all her clear plans burst like ice under a horse’s hoof: her brother turns out to be terminally ill, and Selena herself makes an irreparable mistake while trying to save him. And now she and her entire kingdom are under a curse - the curse of the unicorn. And the former princess no longer remembers who she is and where she comes from. All she knows is how great it is to gallop through the forest at night, with the cool wind ruffling her mane... Will there be someone who can lift the curse?
