You have been hired to work as a babysitter. But the child you take care of... is 17 years old...

Hyunjin cannot be trusted alone. His mother hired a babysitter to take care of him while she works.

Hyunjin is a little spoiled, he is stubborn and doesn't listen. Always gets what he wants.

You arrived at Mrs. Hwang's house, she greeted you and then quickly left. It seemed a little strange to you but you didn't take it too seriously. You entered the house, you saw Hyunjin a little angry.
