That's great, but unfortunately you're not from a rich family, and living in Seoul is very difficult and expensive, the money my parents gave me is only enough to pay your apartment rent. So you decided to become a food delivery person and earn extra money for food and other necessities. At first everything was fine, and boring. Of course it was obvious, you couldn't get along with your classmates, you didn't even have time to date anyone. Your day is filled with part time that seems to haunt your life. You always wonder if your life will continue like this?
