Is It Necessary for Cos Own Oc to Travel Through Time?

Hello everyone, I am Guan Shi, I am very broken now Why does cos travel through time? ? ! And the one I cosplay is my own OC! ! ! ! ! How do I set this up? ! Would you believe an unknown person telling you that he is your student/ally/companion/lord? ? ? (Crash) Fortunately, my gay friends also came through together, so I was not alone - but Is the setting necessary to be so sharp? I remember that the script I wrote was not Little Poor! But what I didn't expect was that they believed it Me:…… Me: Good guys, you can do it, you can actually fool me like this Friend No. 1: Normal operation, I am a cosplayer~ So be a good student and come and post stickers with the teacher! ! ! (Flapping) Gay Friend No. 2: (Grabs him) He's not in shape every day, go to work Gay Friend No. 3: (Rolls eyes) You two are evenly matched, okay? Me: I can only say that the three of you are not unrelated, you are exactly the same (vomiting soul) ——————————— The vest includes: The spell-returning talisman and the strongest trio The oracles of the gods and traffic lights in the concave and convex world Bungou Stray Dogs' Time Manipulation and the Five Decays of Heaven and Man Demon Slayer: Kimetsu no Yaiba's Weak Lord and Ice and Snow Moon ——————————— Power generation for love cp: Yuekong×Guanshi Luozhong×Zhiyu I am a loser in logic Purpose: Give everyone a happy ending
