Fics like Change Your Luck

Simon just wants to pay off the enormous amount of debt he's under thanks to his deadbeat dad who is nowhere to be found. When a stranger appears offering him a flower, and tells him to go to a specific place to change his fortune...he figures why not? He's exhausted from working too many jobs, with no money left over for anything but sparse meals and a shit hole of an apartment. It's silly, but he hopes this means his luck really will change. What he doesn't expect is to be suddenly married and mated to a mobster! Before he can get a single word in, he's been bitten and marked! Cerberus is a wealthy, and powerful Alpha, and now they're mated?! Has Simon's luck changed for the worse, or is this the hope he's been looking for?
