Born at Dusk, Gone by Dawn

[Note: This is an ensemble novel with a time-loop setting. Every character gets a bad ending, with the bonus chapters providing happy endings. It contains multiple couples and is not a pure wish-fulfillment story. The early chapters focus more on narration; once you know the characters and their backgrounds, feel free to skip ahead. No male-male pairings or crack ships, please. If this isn't for you, move on.] [Also: It features a new world order and the existence of people with special traits.]

Two thousand years later, everything has changed. The world has become a collection of city-states centered around Mandes City, and the entire ethical order has been redefined: class, killing, suffering, love and hate, homeland and nation...

It all begins with him.

Born at dusk, gone by dawn, the cycle repeats without end.
