Yu Jiayang (not his real name, shocker), a former conman accidentally caught up in an organized crime's scheme. He was supposed to die at dawn for the sin he didn't commit until a man (Jiayang mistook him for a woman) in a black robe saved him, that was only because he let his mouth ran, spilling everything that he knew about the organization. By everything, it was, well, everything. The man in the robe told him to flee, so he did.
Jiayang is a highly observant man. Bad at names, good at words and has excellent photographic memory. Gambling is not something he's good at, but he knows a thing or two about running a business. It's not necessarily a gambling business, only when his patrons want it to be. When some of his patrons don't want a room and a table to play with, Jiayang has what they need. He has ears and eyes in places the city's security cam can't reach.
work in progress, more to be added soon
