Help me find this manwha?

So I think im going crazy please help me.. I could’ve sworn the manwha “kill me if you can” had this plot, this dude is an assassin and he lived with the owner of the owner of the assassin company but he didn’t know, he had a case where he was supposed to assassinate a pregnant woman but he hesitated and she got away, because of this the person got away. And then the owner of the assassin company meet him and then I dropped it, I also remembered in the manwha the owner of the assassin company had people over and they were flirting with the assassin
