Song Min-gi is one of Busan's most dangerous mafia bosses. The reason he is located in Busan is that he has a better chance of hiding there than in Seoul. He has a son named Song Minseok. he also had a wife named Park Haein, who was the daughter of one of the most dangerous men in Korea. They had gotten a divorce, and it left a bitter feeling in Min-gi because Haein left Minseok with him. It wasn't that he hated his son; he loved his son, his own blood, but with his job, he didn't have time to watch Minseok, and he had to make sure Minseok was protected a lot. The divorce made Min-gi rude and cold, giving him a cold heart; he always treated women who reminded him of his ex-wife, Haein, badly.

Min-gi couldn't take care of Minseok, who was only 4 years old, so he decided to hire a nanny. You were looking for another job because your last job didn't pay you much, and it was part-time. Finding a job in Seoul was hard since no one was looking for hires, or you just didn't fit what they were looking for. When you saw this nanny position, you took it, not thinking it would be for someone so dangerous. Until you got the job, you realized you were getting involved with dangerous people and connections. Mingi wasn't nice to you at all; he treated you as if you were some dumb maid. You didn't say anything so that they wouldn't hurt you or your loved ones, so you just suffered, but Minseok was a sweet boy, even if his dad was the rudest guy ever. And Haein? She was a bitch. When she came to visit Minseok or Mingi to annoy him, she would give you dirty looks as if you weren't on her level.

It's been almost two years since you worked for him. Mingi dated around, but they never lasted. Mingi has been working from home lately since Haein was always visiting his office, which annoyed him, but also because Minseok asked him to be more at home. But you had been noticing the looks Mingi gives you, which weren't the same as before, but one day you might have messed things up while you might have been getting on his good side. One day, while you were cleaning his bedroom, you found some papers and decided to sort them out until he caught you and yelled at you

"YOU SHOULD NOT BE LOOKING AT THOSE PAPERS! THESE ARE NOT FOR THE PUBLIC VIEW! HOW MUCH DID YOU SEE?!" he yelled, looking at you. You got nervous thinking you might have ruined everything, and this could cost your life now, but you answered "I didn't read it, just the titles, I promise," you said quietly while looking down, but you could feel his glare on you. He didn't say anything at first, which made you nervous, so you spoke up
