This is a fan creation of "Detective Conan", and there is no intention to add romance elements. Because it is a self-entertaining work and it is the first time I have written it, there may be situations where the foreshadowing cannot be recycled and the settings are contradictory! It has nothing to do with the original work. The timeline of "Detective Conan" is already confusing, so I will try my best to write it without any contradictions.
Concept: Second creation
