The selfie video, which began in Hakata, Fukuoka Prefecture, was taken for his younger brother in Tokyo. - My younger brother, who had been a hikikomori for several years, started working part-time. - I couldn't wait to hear the report, so I turned on my camera before leaving to see him for the first time in a while. - My younger brother's name is Oz. - He believes in his own talent and doesn't hide the fact that he looks down on those around him. - Naturally, it was on my mind at the AV manufacturer at work. - Then, something decisive happens that makes the situation worse. - Chika, the strong-willed and quarrelsome older sister, mistakes an important person at the manufacturer, the creepy pig man, for being the ringleader of the bullying and makes him fall to the ground. - Oz, who is in a predicament, shifts the blame to his sister, saying, ``It's all your fault that things don't go well,'' and Chika, feeling remorseful, swallows her pride and gives the pig man a blow job as an apology. - The next day, Chika learns that Oz's treatment has improved, and Chika, who is stuck in a deep reincarnation, accepts a fat man's real creampie and even masturbates while taking selfies at home. - Who on earth owned the camera that was secretly filming the whole thing? - What was my sister's real job? - A video recording of a younger brother with a bad personality and an overprotective older sister reveals everything.
