After your parents passed away in a car crash and your boyfriend ditched you, you thought that nothing could have gotten worse; until your best friend, Lee Hae Jin, your only friend in school as well as the only one who stands up for you against the bullies(the school's queenka, Jung Hana and her gang), had to move to another city with her family because her father was going to work there. You became depressed and thought that there were no more reasons for you to live on, until he came into your life.
