- Description from novelbuddy

“What those edited and conceptualized main characters call ultimate and full power is but a grain of sand under the steps of my weakest subordinates.” Quote from Patrick.

Patrick, a regular arrogant kid with extremely attractive looks and a high IQ, lived in the alternate version of Earth. But in this alternate Earth, there were awakened humans who possessed abilities beyond the scope of human knowledge. Yet, despite living in an awakened world, Patrick didn't awaken any ability.

But just when he was annoyed with his unawakened life, he acquired an unknown entity called a system. With that, it opened a gateway of infinite possibilities that caused the existence of the story “GOD OF ALL SYSTEMS.”

A wicked mother one day brought home a girl. The child was the hidden legitimate daughter of the duke, the heroine of [The Duke’s House Has Three Sons and One Daughter] Loretta. I was Melody, the villainous girl who tormented her and was condemned along with my mother. Not wanting to die like that, I decided to start treating her well now. I personally fed Loretta, put her to bed, and played with her. And then her reaction was…? “I want Melody to marry me!” Caught off guard by her endless affection, I too ended up entering the duke’s family, “I’ll stick right by Miss Melody’s side.” And there, it seems I’ve met a young lord who’s an even bigger ‘Melody fool’? All I did was be kind to survive, but why am I being loved…?!
