The first meeting was at a small bar. A friend nudged his arm, smiling somewhat suggestively: A woman like Daisy Ginger should be kept in a vase, constantly admired, and toyed with at any moment.At that time, she seemed to be drunk and was persuaded by her friend to take to the dance floor and perform a dance.He propped up his face, watching the glamorous woman with casual indifference under the dazzling lights.Daisy Ginger.The name is spicy enough.The figure.Also spicy enough.Banyan City’s young Master Wen, afflicted with a severe illness, was deemed by doctors at birth to not live past the age of thirty. He lived capriciously up to the age of twenty-five, never imagining he’d encounter such a dilemma in his lifetime—if he were to die, what would happen to the little demon at home who creates chaos and mischief without his protection, and ends up bringing harm upon herself when he’s no longer there to shield her?

The sky was painted gray forever. The light of the sun was restrained. The darkness of the night was deeper than ever. At such a time, he belonged to a class people didn’t even recognize as ’human’. He was at the bottom of the social stratum, a slave. And when his only family was taken away from him... he no longer had a purpose in life. Yet, he clung to life because of his promise. And he set an impossible goal for himself, just so he’d have an excuse to live. When he finally reached a place he never expected to be, in pursuit of a purpose he expected to fail and die miserably trying to fulfill... he awoke to a night that would change his entire life. He was an insignificant fly, a mere speck in the destruction of the Empire. But he... survived. And, despite being a slave, he gained the blessing of a king. Or rather, the curse...

Though he received the skills necessary to teleport across worlds, the king who performed the summoning ritual attempted to trick him into wearing a slavery collar, this annoyed him so he kidnapped the princess and returned to Earth.
