Transmigrated as a Cannon Fodder Male Side Character, I Eloped with the Male Lead

I drew the cover myself. It shows the protagonist’s appearance in the entertainment-industry world. Bound to a System one day, he becomes a cannon-fodder male supporting character in every world. Shi Yu only wants to quietly fulfill the original host’s wishes, earn points, and go home. Who could have expected... 1. The CEO’s Runaway Sweetheart (modern, wealthy family) Stand-in cannon-fodder top × atypical domineering CEO bottom “I’m just a stand-in! Shouldn’t you go find your one true love?” “Thanks for asking, but I don’t have one.” 2. Rise to the Top in Showbiz (modern, entertainment industry) Popular top treated as a stepping stone × aloof, reluctant-to-promote actor bottom who eventually gives in “Keep your distance. I don’t do promotional couples.” “Come closer, gege. When are we going to get close enough to touch?” 3. After Being Reborn, I Became Everyone’s Favorite (interstellar, ABO) Alpha top whose engagement was broken off × alpha bottom allergic to pheromones “I’m allergic to everyone’s pheromones.” “Then I’m the wonderful exception.” 4. The School Bully’s Boyfriend, a Poor Student (modern, school) Background-character academic top × school bully bottom with explosive pheromones Wait... 1. Quick transmigration, protagonist is the top (highlighted). 2. The world order isn’t set and might change. 3. If you don’t like amateur writing, please don’t read. Theme: The unexpected always catches you off guard.
