There was a special patient in Spruce Hospital. A person in vegetative state and coma that the tree doctor, So Lee-yeon, has been hiding for two years…‘Don’t wake up. Please don’t wake up.’It was her dream to live quietly so she prayed every night. Then one day, by pure miracle or failure, the person in vegetative state woke up!“Did you come to suck this poor bastard’s dick?”In front of the man that lost his memory and common sense, she told a lie that couldn’t be turned as she was afraid of his mu*derous instinct.“I’m your w-wife, Kwon Chae-woo.”To the man who buried someone alive and tried to kill her two years ago!

Years ago, Earth was indoctrinated into the “System.”Earth was not the only place with the System, however. With the System came the other races, Invaders. The Invaders had one goal, to obtain ownership of this new habitable planet. This created a bloodbath, and for years the war raged.This didn't really have much to do with Derek. Derek was kind of a loner. Yeah, he enjoyed the occasional chat or drink with others, but he never stayed in one place too long or really got to know anybody new.Derek did happen to be rather strong. After the years of fighting monster and Invaders alone, he had become quite adept at surviving. One thing that helped keep him alive was his refusal to get involved with others. He rarely cooperated with teams.One day, Derek broke his rules and decided to lend some help, as the mission didn't seem too hard. He should have stuck to being alone.

I was a genius in the Earthen Plane.
