The beautiful CEO falls in love with me

Once, he was a spectacular man.Once, he was a heroic figure standing tall.Once, he was the heir to the world's most secretive family.When it all ended, the hero lost his memory and indulged in the city...Now, he becomes a contractual slave in the hands of a female CEO.Now, he leads a group of underlings down a dark path.As the hero awakens and the horns of battle sound, a mysterious veil is lifted, and he is destined to be a figure that makes the Earth tremble.
