I'm Actually an Interpol Police Officer

If you book friends have any good supporting characters, please tell me and I can write them in the book. (This way I don't have to think hard about supporting characters.)

Uh... I would like to give you some suggestions. It is better to put the suggestions and comments at the end in the words of the author at the end, otherwise it will be a bit strange. At least give a dividing line, otherwise it will be too dramatic. Of course, it is just a little suggestion. Whether you adopt it or not is up to you.
