Yang Jun-myeong

Hae-young is a hopeless girl. She lives with her father who runs a Chinese restaurant, and a younger sibling. One day, her father has a mysterious accident, which places her in a position of responsibility. She is now not only the head of the house and must look after her younger sibling, but also an investigator tasked with finding the truth about the accident, and a fighter standing against the ugly world.

Over ten years ago, their mother passed away after giving birth to the youngest sibling. Not long after, their ailing father also died. Now, with an eviction notice in hand, the four siblings are left with only a letter from their father and a car registration under Chun-ja's name. Chun-ja takes back the car that their uncle had been using. After a family meeting, they agree with Jun-myung, the third sibling, who wishes to take a year off from school to travel. They set off on a camping journey together.
