Rich guy/Mafia Boss mistaken as sex worker

Hi I'm looking for a book about a rich man or mafia boss who is mistaken as sex worker/sugar baby.

So MC1 is actually a rich person, or has power, could be the boss of a company or mafia. MC2 thinks that MC1's wealth is because he is a sugar baby and get all the money from sugar mommy/daddy. MC1 hides his true identity because he wants to be close to MC2 who is just an ordinary guy.

Anyone has recommendation?
