I'm a Big Shot in Every Parallel World [Crossover]

"I'm the Only One Without a Big Shot in Any Parallel World" As the protagonist of this fanfic, whether it's skipping grades to get into Cambridge or having superpowers found in ordinary comics, like telepathy, willpower, X-ray vision, precognition, and teleportation... I have none of them. I'm an "ordinary person." Then I wake up one day to find my world has changed. They tell me I'm the fiancee of the boss of some seafood family / the monster leader intent on leading his underlings to seize Kyoto / the great demon king who's going to slaughter the world. To save the fragile dimensional barrier, which is as flimsy as paper, I also have to keep my character from falling apart (smiling through the exhaustion.jpg). #I'mTheOnlyNormalPersonInTheWholeWorld# #AllMyParallelWorldSelvesAreBigShotsAndTheyLeftMeThisMessToDealWithWhatDoIOnlineNowHelp# #OneSecondI'mSavingTheWorldTheNextI'mTheVillainBossBreakingUpSomeonesShip# In the end, the dimensional barrier still broke. While all the guys from opposing factions crowded outside my door and started fighting, they also asked me what I thought. I decided the world was beyond saving. We might as well destroy it. Reader's Guide: [1] The heroine is doted on by everyone. The male lead appears at age 270, but is more of a background character. [2] This story took a long time to finish, and the heroine's personality changes somewhat over the course of the story. [3] I didn't plan the outline well while writing, so I wasted some good ideas. I might rewrite it someday. Theme: Have a proper understanding of yourself
