Believe it or not, Yun Seah had always told herself that the world revolves around two types of being. The Lighters and the Shadow Walkers. Ever since she was born as Shadow Walkers, she never encounters the Lighters. With almost similar features and speech, these two beings are different in so many ways that only Shadow Walkers know. Yun Seah is very aware of the existence of Lighters as they were taught about Lighters at school but Shadow Walkers were never known to the Lighters. As if they are just a myth which no one even care about. With the knowledge she always carry on in which she thought she knows everything, she never prepare herself to finally meet the pale and quiet Zhang Yixing whom she found absolutely enticing whose hiding under her bed one day. For she know that he is the Lighters who came intrudes the land of Nightless and the Moon Caster is out to get rid of him.
