In 2006, high schooler Park Sae-Ro-Yi (Park Seo-Joon) was jailed for 2 years after attempting to kill Jang Geun-Won (Ahn Bo-Hyun). Geun-Won is the son of Jang Dae-Hee (Yoo Jae-Myung) and heir to the Jangga Group (Korea’s largest food corporation). Because of the Jang's influential power, Geun-Won leads a spoiled life and is able to bully people with impunity. Park Sung-Yeol (Son Hyun-Joo), Saeroyi's father, worked for Jangga and sponsored Oh Soo-A's (Kwon Na-Ra) education. Saeroyi had a scuffle with Geun-Won because he bullied Lee Ho-jin, Saeroyi defended Ho-Jin by hitting Geun-Won; it got Saeroyi expelled. Sung-Yeol supported his son and resigned from Jangga; father and son would try to open a bar to restart their lives. One night, Geun-Won irresponsibly crashed and killed Sung-Yeol, but Dae-Hee had someone else take the fall; Saeroyi tried to kill Geun-Won for his father but Soo-A (classmate and first love) stopped him. He was arrested and tried guilty for attempted murder and assault. Dae-Hee always offered mercy if Saeroyi kneeled, but he refused out of principle. Motivated to get revenge, he survived his sentence and vowed for vengeance. [cont.]
