One is named Su Le and the other is named Shadow Moon.
One is the youngest son of Obasan in the inn. He is enthusiastic and simple, optimistic and kind. He always believes that the sky is blue, the clouds are white, and the human heart is made of flesh.
One is the product of the intrigues in the dynasty. It is gentle and harmless, gloomy and unstable. It never trusts anyone. It fights for what it wants and gets rid of those who make it unhappy. Only darkness is right in the world.
(O_o. No responsibility novel. It is purely for leisure.)
