Doing Sit-Ups in the World of Detective Conan

"Aaaaaah! Why can't I lie flat even in an anime world?"

Lin Mu is a laid-back college student living in the 21st century, spending every day wavering between rat-race burnout and lying flat. A chance encounter transmigrates him into the world of anime. He thinks he can finally be a lazy fish who never has to turn over, but it turns out he's still doing sit-ups.
