The world of Onyx was normal, with its sky cars and regular air travel. The three moons revolved around the sun, until one night. That was the night the moons never appeared, the sun still high in the sky and by the the next morning, everything would change forever. Hyeongjun had heard that things would change, and now things were, right after a strange man had shown up, speaking of a planet called Earth, a place he would take them all to. 

They say monsters don't exist. Chenle always believed that, until he saw what his boyfriend had written about killing people in his town. No one else had seen it, and they wouln't believe him, if he had mentioned it. Now he must decide if he'll risk sounding insane and tell Jisung to stop writing his story. 

Sungjong lives in a world where everyone gets a chance to live another life. Legends say it started because of one's good or bad karma, but no one knows for certain. After several lives, he meets someone special...with an infinity symbol, instead of the typical, evergrowing tattoos that show the number of lives. Myungsoo is different. 

When Daehyun loses someone close to him, he immediately suspects Youngjae, the town rogue. He hunts Youngjae down and finds him, but not before someone else does and curses them both. Now they will be tied to one another's lives in a way they would never expect...They must stay together to survive.
