Mark is interested in most businesses, he helps the mayor manage the mayor's assets, and of course, this is not illegal.
In the Bail Federal, it is not illegal for a politician to have his own business. Many merchants suddenly feel the weight on their shoulders during their business journey, or they have some good ideas to help more people prosper, and they will turn from merchants into politicians.
They do not have to sell all their holdings just because they become politicians, nor do they have to cease any commercial activities.
In the Bail Federal, there is no such standard; the only thing those with role changes need to pay attention to is not to use their power for personal gain, that's all.
The mayor entrusting his assets to Mark for management is mainly to avoid suspicion, just like people don't really urinate or defecate on the roadside just because it's not explicitly prohibited.
Though doing so isn't illegal, it always leaves a bit of a... feeling.
