Are you sure the babysitter is a man ? The description you've given reminds me of Mafia Nanny , its a webtoon tho...
Hope this helps (๑•ㅂ•)و✧
Yes I think this is it!!! Thank you ヾ(☆▽☆)
The manwha has been found but thank you very much anyway (≧∀≦)
This manwha is about a mafia boss who has a kid and the kid really likes this man (the main character) so they get the man in to babysit and I think they do a body check of him before they let him in I don't remember much after that but the mafia boss isn't interested in MC at first I think
