A woman in weird clothes suddenly appeared in my room, announcing herself as Space Angel Boinboin. She opened that that she came from a planet a thousand light years from the earth. Offering a stunning fact that as a result of genetic research, I would be an arch rogue in the future. She came here to keep from occurring tragedies that would happened if i had grown up that way. How could I believe the crap!? I am such a wimp, a wimp with small body, voice is too weak.... She didn't give a shit about how I feel of my destiny, forcing me to have sex in the name of rehabilitation, no matter how much I'm tired..... [From DLsite English]
