"Comprehensive" Nakahara Chuya 2/1

Nakahara Chuuya's modern mother is a loyal fan of Fumino, and it happens that his foreign father's surname is Nakahara, so he has the name Nakahara Chuuya. When Chuuya was 13 years old, he was dragged out of Fumino Nakahara Chuuya's cosplay by an enthusiastic gay friend. Because he was born a mixed race, with blond hair and blue eyes, Chuuya saved money on contact lenses. She touched her purse that had been half-emptied and felt heartbroken, but she finally bought the tutoring R18 book. What I didn't expect was that I just changed into a cosplay costume and traveled through time. I just wore it, and even my hair color was automatically dyed. What's going on? Moreover, the tutoring notebook I just bought before I took a look at it turned completely into a small white notebook, which was a devastating blow to Zhongya. After returning home, Chuuya fell silent when he met a classmate named Tsunayoshi because of the transfer. When he was told that his parents said he was a member of Vongola, and that Chuuya was actually assigned the task of protecting Tsuna with other secret bodyguards, Chuuya fell silent again. I'm just a weak girl who bumped into Fumino Nakaya and asked me to be a bodyguard? ? But it wasn't until he met a black mud man walking on two feet that Chuuya found for the first time that his good emotional control line was suddenly broken. As soon as he stretched out his feet and stepped on the ground, cracks opened and stretched. Chuuya raised his head and grabbed his collar unceremoniously and pulled him down. I even gave him a nickname casually. "Huh? It's so rude of you, a mackerel, to call the girl you met for the first time a slug!?" Note: In the parallel world where Chuuya travels through Tutoring and Bunno's world, the male protagonist may be Tsunayoshi or Dazai, or there may be two endings. (Back!) The extras can be viewed as different stories for the time being. Intent: Light-hearted novel [probably]
