Do you recommend novels where the male protagonist transmigrated into the anime world? It's best if it's already finished and there's no harem?

😋I recommend the novel "The Genius System of Infinite Animation" to you. It's a novel about the infinite universe. The male protagonist started as the student council president in "Angelbeats" and then grew up in various anime worlds. This novel is already finished. There is no harem. I hope you like this fairy's recommendation. Muah ~😗
