Writing a Diary in Beika, I Break the Detective World?

Su Yi transmigrates into the world of Detective Conan, and gets everything just by writing a diary!

Just by keeping a diary every day, he can get houses, money, mastery of crime-solving, firearms, and languages. He even gets magic?

He is only a photographer, and all he originally wanted was to photograph the many beautiful women in the world of Detective Conan and add them to his collection.

If he could win the favor of one or two of them, that would be even better!

But he never expected every character from the original story to go completely off the rails!

Why hasn't the shrunken Shinichi Kudo moved into the Mouri Detective Agency? Why is Kogoro Mouri going out of his way to pick on him instead?

Why didn't Shiho Miyano seek out the shrunken Shinichi Kudo? Instead, she played the victim and moved into his home?

Why is Vermouth so eager to get him into the Organization that she's even giving him all sorts of liquor-themed code names?

Why did the Phantom Thief Kid come to his door and challenge him to a fight?

What on earth is going on?

Surely he should know them, while they don't know him. So why does it feel like these people are just a little too familiar with him? This novel and its characters are entirely fictional. Any resemblance to actual people or events is purely coincidental. Do not imitate.
