Detective Conan: There’s Nothing Wrong with Liking Vermouth

[Infamous + System + multiple heroines + everyday life] One day after taking the graduate school entrance exam, Gu Yuan is reborn in a new world. With an extraordinary physique and a talent for learning, he thinks he can live out his life perfectly. Who knew his parents would die in a car accident? Then he learns that his parents were members of the Dragon Group? A year later, while traveling in the United States, he meets Vermouth and discovers that this is the Detective Conan world. Vermouth takes a liking to him and brings him into the Organization. Then a “garbage System” awakens. From then on, in the world of Detective Conan, he makes up for a few regrets, teases Conan, and even provides the Dragon Group with some intelligence along the way? Conan: “Gu Yuan is on our side, right?” Vermouth: “No! He's on my side.” Really, it's just a former useless medical student who wants to live freely and do as he pleases in a new world.
