Webcomic Name?

So, I read a Webcomic on WEBTOON Canvas years ago. It was about a young blond girl who was adopted into the mafia. She’s incredibly intelligent and is constantly having her life threatened. I think the first chapter even as her limo and escorts being blown up with her being the only survivor. She’s end up teaming up with a tall, muscular blue haired guy with amazing powers and limited understanding of the world (he may have tried to eat a door) The last arc I remember was taking place at a hotel. That’s all I can remember.
