Chance and Mafioso

Chance once got into debt, but he couldn't pay it off. The debt was paid, but what about the interest? No one talked about it, so debt collectors from a very scary mafia, which I haven't been able to catch for several years, started chasing Chance. Chance easily eluded the debt collectors, so the head of this mafia, known as Mafioso, or perhaps Don Sonnelino (I don't remember his last name exactly, so if anyone knows, please write it down), began lurking behind him. Chance found it difficult to escape him, as he was literally following him around. They ran like that for a year. Chance did pay some money, but it was still not enough.
One day, they stopped chasing Chance. He no longer felt someone's gaze on him, or their presence in the empty alley, as if they had vanished. Chance became... Bored, perhaps? If those escapes from the mafia had given him any adrenaline, now it had become too boring and uninteresting. After a while, Chance's conscience began to gnaw at him (and did he even have one?), and he finally decided to return the money he needed. After winning it at the casino (he hadn't earned it, after all), he went to that mafia...

Mafioso (Don Sonnelino) is the head of the local mafia, terrorizing the entire city. He has soldiers (the Collectors): Boris, Ian, Ethan, and Lucien. They are all very kind and cheerful, except for Ethan, but they all equally love pizza. He has black hair and burgundy eyes, and is 210 cm tall. He wears a fedora hat, which usually hides part of his face. He is a serious and responsible man. He is jealous. He loves rabbits.
