Cleaners in the World of Conan

I don't understand why the protagonist has a conflict with Kaitou Kidd at the beginning. I can completely ignore it. This part is a bit deliberate. It's a bit awkward to forcefully pretend.

The writing is so confusing that I can't see the theme clearly at all.

The protagonist doesn't know about Conan? And then it's also fake wine?

The book is quite good, but it's a pity that the author has passed away and has stopped updating. I'm sweeping the grave\|/

Something like this

The front part is too messy. I feel like the author is trying to draw out the characters, inexplicably letting a bunch of people pass the line, and he can't even understand the main line. He was said to be a cleaner, but there was no relevant description at all, and he was directly dragged into a conflict with Kaitou Kidd for no reason. So what is the point of letting Gin and Vodka take over the protagonist in the beginning? The writing style is similar to my comment. After a long thread, the train of thought stops. Don't follow it.
