sooo....im in desperate searching for the title of this one novel in which the mc travels from one world to one world in order to destroy the so called protagonists in every world he comes. and i remember this particular world which is live streaming idol (?) the original body before mc takes over is a live streaming idol in extreme sports, so does the protagonist. then both of them enter a big competition for extreme sports live streaming,,, the participants were took to a forest where they need to survive from the wild animals, cook themselves food and etc. after that , the protagonist sabotaged the original body by putting something in his parachute, making the original couldn't land properly and break his bones. he after that was disqualifiedbcs apparently someone accused him cheating(?) and didn't even get any consolation prize. then the original was paralyzed and later died on the hospital bed, after watching the protagonist won the first prize. mc takes over the original's body before he participates in the competition. oh and the male lead is a director / sponsor for the competition. (i am sorry for my english huhu )
It isn't "There Will Always Be Protagonists With Delusions of Starting a Harem"? It's a system user novel so there's world hoping and he's sabotaging the protagonist
