Shiita and Eisei, childhood friends, and twins Kiou and Rio, who were classmates in high school, are members of the popular MeTuber group "Parasite Party." One day, during a prank live stream devised by the twins, it was revealed that Eisei is gay and has always had a crush on Shiita, causing a rift within the group. Shiita, a womaniser at heart, struggles to repair his relationship with Eisei, but Eisei confesses his feelings to Shiita again and, as if defiant, pressures him into a physical relationship, saying, "Maybe if we do it once, a new door will open up?"—!?

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.
