Ohoh, I have a good answer this time !

WoL is inspired by a french fanfiction Harry Potter, Alternative Univers ! Where Tom is a mafia leader and Harry, a Law Student ! (with Father and Godfather in the police station, mother an attorney, etc).
Tom was well writing, not too soft but not too psychopathe I guess XD And the duality in Harry was interesting ! (his love for Tom, the bad things the man do, his parents in the right side of the law, etc)

Well, now, you can guess who is the inspiration for the Dimitri and Harry's charadesign x)

I didn't take all the details in HP, nor all characters just the bases. I can't make too complicated stories x')

Voila !
