After Losing His Memory, 270 Became My Ex-Boyfriend

What do you do when you wake up ten years older for no reason, facing off against your childhood friend with weapons in hand? Tsunagawa Natsuaki stared at the 270 in front of him, lost in thought. The good news: His childhood friend had become the mysterious boss of the Vongola. The bad news: He'd lost his memory, had no idea why his childhood friend had become his ex-boyfriend, and was now pointing a gun at him, trying to blow his brains out. Even better news: The idiot System in his head, which kept saying it was going to "eliminate" him, was gone. [Beep. Player [Tsunagawa Natsuaki] detected interfering with a plot point. System punishment triggered. This punishment: tenfold electric shock.] I'm Tsunagawa Natsuaki (Kamei). I'm an ordinary high school boy, born in an orphanage. My codename at the orphanage was "S." I don't know if it was something special about the orphanage or what, but as far as I can remember, our orphanage had an astonishing number of geniuses. Obviously, I was one of them. "You really don't look like you want to live," the bandaged weirdo said, thoughtfully rubbing his chin. "Of course I do!" I declared. "I'm the most life-loving normal person in the whole world, just like you, Bandage-kun." The bandaged weirdo looked disgusted, as though I'd offended him. "I don't think a normal person would slap the table and yell 'Objection!' when they know that Byakuran-kun is at the end of his patience and has a gun pressed to their forehead, then walk away completely unscathed." My good buddy +1 protested weakly, holding up a surrender sign. I pretended not to know what he was talking about and looked up the text messages I'd written in my drafts over the past five years, but never sent to someone labeled "ex-boyfriend." Then I answered enthusiastically, "Can't help it. I'm completely devoted to my boyfriend." The head of the Pan Star Cult: Would you dare say that in front of 270-kun? Reader's Guide 1. CP: 270. By the time the main story begins, he's been in the mafia for a long time. 2. The main story takes place ten years later, but there will be lots of flashbacks about Natsuaki's ten years. 3. This is a fix-it story. None of the good guys from any of the franchises mentioned above will die. 4. This story does not welcome any slander of original characters or promotion of made-up words. Theme: Good kids, cherish your lives :D
