Happily Ever After Cafe discussion

Okay so this is vague, I know, but a couple of years ago I read this mafia (Russian maybe) series and all I can remember (I was in a phase at the time and the stories kind of blurred lol) is the MC of the first book was nicknamed Satan or The Devil and he brings the female MC to his home, where they fall in love. The follow-up books each feature one of the men who work for the MC. Steamy and suspenseful but not disturbing. The books may have been titled with the names of the character featured. That’s all I’ve got. If this series rings a bell lmk!!! Thank you!
