On the Eve of the Wedding, Xiaolan Ruined Conan's Last Antidote

Conan (It Would Be Better If the Male Protagonist Also Becomes Smaller)

Detective Conan Fan Fiction

I want to read a book like "I am writing a novel in Mingke, if you mess with me you will be the heroine". Black or half-red and half-black. The protagonist should be a female. It's more fun. If possible, I hope the protagonist is a child. There is no CP. I don't want to split the official match. Can it be funny? (●°U°●)
