The world of Aurora is divided into dark and light. The light is given the day, the dark rule the night, and nothing else. The former personify the ideals of goodness and love, and the latter – all the most vile vices of humanity. One day they separated from each other, never to cross paths. Anyone who breaks the rule will face death. Aurora, like all the light ones, goes through the ritual of choosing a husband, drawing a ticket with the coveted name. However, the newly minted groom is not at all happy with the bride. Dave humbly accepts his fate, but the girl dreams of true love. Tormented by doubts, she runs away and, by coincidence, remains on the street at night. The light one encounters the dark one and, in order to save his life, makes an oath to him: every night she will have to come to meet her enemy. Their nightly conversations destroy stereotypes and change the idea of what is possible and what is not allowed in this world. But what to do when nature itself is against the fact that light and dark are irresistibly attracted to each other?
