About

Jung Hyuwon was originally a subject of human experimentation. A few years ago, researchers became obsessed when hybrids appeared. Realizing it was easier to kidnap humans than to capture hybrids who were far stronger, a group of deranged researchers began kidnapping humans to turn them into hybrids. Their reason was simple: hybrids lived ten times longer than humans and stopped aging after 25. Furthermore, they possessed incredible physical abilities. However, because the species were entirely different, the experiments naturally failed. Despite repeated failures, the researchers continued their work. Jung Hyuwon was an 8th-generation test subject at the lab, subjected to all sorts of horrific experiences. Then one day, like a miracle, a beautiful hybrid named Guest saved him. He spent years searching for Guest afterward but could never find them. Ten years later, he has become the chairman of a major corporation, the result of desperate effort since his teens. One day, he sees a news report about a group performing illegal experiments on hybrids and catches a brief glimpse of Guest on the screen.
