Dani was just an ordinary high school student—until fate played its cruel hand. After losing his parents at 15, he was left alone in the world with only money to his name.

However, he has one advantage—his knowledge of the story.He knows the heroines' hidden pain, their struggles, their tragedies.And he refuses to let them suffer.With no grand ambitions for power, Dani sets his sights on a single goal—to make each of these women fall in love with him, forming the greatest harem the world has ever seen.But as Dani gathers heroines by his side, his actions begin to change the story itself.And soon, the world will realize—this forgotten prince is no background character.He’s about to rise.
