This drama is based on a webtoon by Kwon Laad (권라드) which was first published in 2018-April-17 via Daum Webtoon Company.

It’s about the “contract friendship” between an ordinary high school student and a young man known for using excessive force.

Park Chan Hong (Lee Shin Young) is an ordinary high school student. He has talent for writing and he gets pressured by his parents about his studies. Park Chan Hong doesn’t have any specific dreams. He is friends with Uhm Se Yoon (Kim So Hye), who attends the same high school. She is popular at school. Meanwhile, Heo Don Hyuk (Shin Seung Ho) is classmates with Park Chan Hong. Heo Don Hyuk is not interested in studying and he works to pay for his living expenses. One day, Heo Don Hyuk saves Park Chan Hong from a school bully. To pay for his rent, Heo Don Hyuk asks to borrow 300,000 won ($270 USD) from Park Chan Hong. Park Chan Hong lends him the money, but that money was supposed to pay for his private institute tuition fee. After school, Park Chan Hong now doesn’t have a place to go. He begins to spend time with Heo Don Hyuk.
