Usogui & Kurosagi but its just me drastically overthinking the pseudo father/son relationships

Turns out "pretty, morally dubious, scam artist adjacent kings who have a sweet tooth and their father figures who play both sides of the criminal world they occupy in Japanese media from 2022" is now one of my favorite dynamics. Kurosagi I'm at least justified bc their relationship is a plot point but Usogui? None whatsoever, yet I do be thinking about them a lot!!! A fanedit of Usogui 嘘喰い and Kurosagi / The Black Swindler.
