[Jujutsu Kaisen] Wait, I'm Not the Main Character??

Ever since he was little, he could see the horrifying things other people couldn't. As he grew older, Zhinian Qinnan's state of mind changed from [afraid] to: I'm invincible under heaven. A major factor behind this huge change was all the hot-blooded shonen manga in Weekly Shonen Jump. Even when he was fifteen, acting arrogantly like [Come on, hit me, you supporting characters] and getting beaten to the ground by a white-haired Jujutsu Sorcerer, who carried him off to the technical college like a chick, he still kept his incredible confidence after his classmates gave him a series of inexplicable beatings. [I'm invincible. Do whatever you want. I'll win either way.] Then, at sixteen, he went to an ordinary high school to retrieve a Special Grade Cursed Object. He saw an "ordinary" fifteen-year-old high school student swallow the object and keep his sanity, a textbook protagonist moment, and was utterly shocked. [What? Am I not the main character?] [Could I be the villain?] Satoru Gojo: "No, you're just an ordinary background extra." [? I'm defecting! If I can't be the main character, I'll be the big bad villain!] Yuji Itadori: "Senpai, thank you!" "Huh?" He was just about to put on a villain's face to get more screen time when Yuji Itadori rushed over and hugged him. [What is this? Why is the protagonist so enthusiastic about me? Could I be the Sasuke-type second male lead?] [Could my Orochimaru be you, Mahito?!] Mahito: "Stay back! Don't touch me! I know you're imagining things, so get away from me! Your cursed technique can hurt me! Get lost!" Written on a burst of inspiration. Zhinian Qinnan is a certified idiot. Message: Cuddle up.
