Afflicted with an illness at 25, my life should have ended when I was 26 years old. However, when I came to, I had become a 6 year old boy. Not only did I have my past memories, I also retained the memories of my current body that I shouldn't have. Recognizing the six years of memories, I recalled immediately. The world I had awakened in was a world I'd read about in a shoujo manga in my previous life. It seems I'm on a parallel world trip . . ? No, I have reincarnated. At the same time as I recognized this world from the shoujo manga, I remembered my status. In the story, I was the subordinate of a stalking horse who fell in love with the heroine. To compete for the hand of the heroine, by the stalking horse's orders, I got involved by implementing various interferences to all the other love interests like the prince and sons of dukes which resulted in the death penalty. The stalking horse didn't even bother to protect his subordinate and covered up his own crimes.
