ISO mafia romance with regular-life FMC and “strong mafia man” MMC

I’m looking for recommendations where the MMC is in the mafia in any capacity (top guy, middle man, low level, whatever) and the FMC is a regular girl who has a regular life.

They happen to meet & how their romance builds doesn’t really matter.

What i’m looking for is for the FMC to not take the MMC seriously about his mafia life. Like, she sees his as a big strong guy acting macho and thinks it’s funny or even cute. She thinks some of his quirks are impractical but that’s because she really thinks he’s a regular guy - she doesn’t believe he actually has any ties to the mafia.

How she comes to grips with reality doesn’t matter, i just want the scene to be like: “Oh you were being fr this whole time O.O”

And he’s just like: “…yea…”

And then they fall in love/continue to be in love and have a happy ever after.

Thanks for any and all recommendations!! <3
